This story will sound familiar, but it's not a repeat. A month after AOL's Ryan Block posted an audio recording of a Comcast cancellation call that even a Comcast executive called "painful to listen to," another customer has posted a video showing how difficult it was for him to cancel service.

Chicago resident Aaron Spain explained in the video Monday that he was on hold for more than three hours, showing the time of the call on his phone as proof. He was calling to cancel Comcast "after a month of trying to get them to fix my service," he said. Spain was transferred to the retention department, but didn't actually get to talk to anyone. After using a different phone to call back the same number, Comcast's automated assistant told Spain, "I'm sorry, but our offices are now closed."

Comcast admitted fault, telling news sites today that “Under no circumstances is this the experience we want our customers to have. Our goal is to be respectful of our customers’ time and fix any issues the first time. We take this very seriously, and after investigating Mr. Spain’s situation, we want to apologize to him and acknowledge that his experience was completely unacceptable.”

Spain was able to cancel his service the day after the three-hour hold time, he wrote on Twitter, adding that he hopes "they still honor the credits I was promised."

After his story spread around the Internet, with his video being viewed nearly 450,000 times, Comcast's upper echelons sprang into action. "Wanna hear a funny story? @comcast corporate called me, call dropped, called me back & left msg they were closing but would be in tomorrow," Spain wrote just a few hours ago.

This isn't even the first time this week Comcast has apologized publicly for a bad customer experience. Customer Tim Davis was charged $181.94 in apparently bogus installation fees and was only able to get a refund because he had recorded a previous phone call in which he was promised that the work would be performed for free. In that case, Comcast said, "This is not the type of experience we want our customers to have, and we will reach out to Mr. Davis to apologize to him."
