Refund not issued - over five calls

My opinion of your company was already at rock-bottom, but we've sunk further into the ocean. My HOA stated to us that we were transitioning to a bulk service, and that in April, the Xfinity charges would be through the HOA fee instead. In April, I was charged for service even though I had already paid my new HOA fee. I called, and said to remove the charge, and they said they would and did not. The same thing happened in May. I removed autopay myself, and have called over 5 times, spent literal hours on the phone with your representatives to resolve this issue to no avail. It is absolutely astounding to me how a company that profits $14 billion dollars cannot find it in their coffers to spare $138 of overcharges to someone who has been a lifelong customer, even if it's against his will. I am seriously considering contacting consumer protections about this irresponsible behavior.
