I called in to cancel my Fios Internet service back in March. The service discontinued on 3/15 and the representative said that my final bill would be adjusted to reflect changes. Even the cancellation email said I would receive final bill/credit as adjusted. However, I was still charged the full amount for March/11-April/10 on the auto-pay date. I called customer service who insisted that the service would be charged for the full month whatsoever and would not be prorated. She said I could dispute via credit card if not happy.
I was sick of calling Verizon again and again without having the problem solved, and disputed the charge (I actually prorated myself just to be fair) with my credit card company. The bank credited my account (after investigation as I sent in the evidence I had), but my Verizon account now says “returned payment” and asks me to pay that disputed amount again. If Verizon so firmly believes that I’m obliged to pay for some service that I didn’t receive, why couldn’t it deal with the bank about the dispute and stop harassing a customer?
