You'll think good customer service is an oxymoron more than ever after listening to this testy exchange.

Ryan Block wanted to disconnect his Comcast cable service, which turned out to be very difficult because the Comcast rep who took his call had a real problem taking "no."

And when we say "very difficult," we mean it. Trying to solve a Rubik's cube one-handed while blindfolded isn't as frustrating as dealing with this guy.

As Block said,  they had "already played along and given a myriad of reasons and explanations as to why we are canceling (which is why I simply stopped answering the rep's repeated question -- it was clear the only sufficient answer was "Okay, please don't disconnect our service after all.")

Comcast had to do damage control after this fiasco generated some publicity by issuing an apology.

For his part, Block is keeping a level head and asked Comcast not to fire the rep. If they do let him go, he can always go into telemarketing.

Check out the intense call below and compare to your own crazy experiences with customer service because you know you've had them, too.
