Yes. And I signed up for AT&T DSL when their ad said “cancel anytime; no penalties”. When I cancelled, I received a cancellation bill and a letter saying “come back, remember we’re the company that doesn’t have cancellation fees” in the same day.

I tried to dispute the bill and they sent it to collections. Also, during signup they ran a hard credit check explicitly against my permission. One person vs BigCo doesn’t always work out.
