Comcast Business: a case study in broken promises

Why I’m writing this one

I rarely write posts like this. But my experience with Comcast Business has been frustrating enough that I feel obligated to document it, both for transparency and to warn anyone who is considering their service.

The whole thing started with the salesperson who handled my move from residential Xfinity to Comcast Business. From the beginning I was very clear about my priorities. Upload speed was critical for my work. I also asked specific questions about how the transition would happen, what equipment would be affected, and what I would need to do on my end.

What I was told and what actually happened turned out to be two very different things.

The “automatic” transition that wasn’t

I was explicitly told the transition from Xfinity residential to Comcast Business would be automatic, seamless, and painless. It wasn’t.

My residential service didn’t disconnect on its own. When I called in to cancel it manually, I was told I would be charged a $160 early termination fee. That was especially frustrating because I wasn’t leaving Comcast at all. I was switching directly from Xfinity to Comcast Business, on the guidance of their own salesperson. At no point was I warned that this “automatic” transition would trigger an early termination penalty.

I then had to spend more time arguing with Xfinity support to explain that I was not leaving the company, only moving to their business service. After going back and forth, they agreed to credit the $160. But the fact that I had to fight to undo a charge that should never have happened in the first place says a lot about how poorly this transition was handled. And this was only the beginning.

The streaming box that died on day one

This one caused real frustration at home. I asked multiple times whether my streaming box would keep working after the transition. I was reassured every time that it would.

The moment my Xfinity service was canceled, the box shut down completely. My girlfriend suddenly had no access to her shows, and I had to leave the house and buy a 4K Roku just to restore basic functionality. That is an out-of-pocket expense that never should have happened if I had been given accurate information. On top of that, I had to return the old equipment myself.

The upload speed nobody fully disclosed

This is the most serious issue in the whole experience. From the very first conversation I made it clear that upload speed was a top priority. My work depends on it, and it was one of the main reasons I agreed to switch to Comcast Business in the first place.

Despite that, the salesperson failed to disclose a critical limitation: the 500 Mbps plan only provides 35 Mbps upload. That alone makes the service a poor fit for my needs.

What makes it worse is that I was also told I was in a “next-gen” service area, and that higher upload speeds and expanded capabilities would be available soon. It was presented as reassurance: even if the current speeds were limited, the infrastructure in my area was already being upgraded.

After things started going wrong, I followed up with several other Comcast and Xfinity technicians and managers. Every single one of them confirmed the same thing: there is no confirmed timeline, no scheduled upgrade, and no guarantee that higher upload speeds are coming to my area anytime soon. In other words, the “next-gen” claim that influenced my decision to switch simply wasn’t true.

This was not a minor misunderstanding. It was a core technical detail that determined whether the service met my requirements, and it was either withheld or misrepresented during the sales process.

No accountability, no follow-up, no resolution

After all of this, I emailed my original account manager with a very reasonable request: a $30 monthly credit for 10 months to offset the inconvenience, the extra costs, and the misrepresentation.

I never heard back. I followed up multiple times by email and phone. Still nothing. I escalated to his manager. Also nothing. Over the course of this situation, I spoke with more than six different support representatives and multiple managers. Every conversation ended the same way: polite apologies, promises to “look into it,” and no one actually taking ownership or attempting to make it right.

Canceled without a fee, billed more anyway

Just when I thought this experience couldn’t get more frustrating, the cancellation process delivered one last surprise.

To Comcast Business’s credit, I was able to cancel without an early termination fee. There was no contract penalty, and I appreciated that. What I was not clearly warned about is that cancellation requires a 30-day written notice period. Here is where it becomes absurd.

Even though I had returned all the equipment, turned off the service, and stopped using Comcast Business entirely, I was told I would still be billed for another 30 days, and not at my original rate. They plan to charge me $15 more per month than my original service cost, for a service I am no longer using, with no equipment and no active connection.

So: I am no longer a customer, I have no active service, I returned all the equipment, and I canceled without a termination fee. And I am still being charged a higher monthly rate for another full month anyway. At this point, it is hard not to see it as intentional.

Closing thoughts

This entire experience, from the misleading sales process, to the lack of accountability, to the hidden technical limitations, to the cancellation billing, paints a very clear picture of how Comcast Business treats customers once the contract is signed.

If you are considering Comcast Business, my advice is simple:

1. Get everything in writing before you agree to anything.
2. Confirm every technical detail yourself, especially upload speed and coverage.
3. Ask about cancellation terms and notice periods up front.
4. Don’t assume billing stops when your service does.

Because in my case, it didn’t.
