Redditor Awwwsnack was so frustrated with his troubles getting Comcast service installed that he decided to cancel.
But you can't just call and cancel. You have to speak to one of their infamous retention specialists. The person he was speaking to put him on hold, and he waited... And waited... And waited... Three hours later, still on hold, he called back with a different phone, only to be patched through to a recording saying that the office was closed. He was still on hold.
