I upgraded my device and sent the old device back. When it was time to pay my bill on 6/20/2022, Verizon charged my bank account the remaining balance of the phone which was $549.96. I called and informed customer service that they are in posession of the phone and I was over charged. The rep checked the system and saw that the phone was indeed returned and I was unjustly overcharged. I was then told I would have to wait until July 05, my new billing cycle for the money to be returned to my account. I waited. While I waited I made many phone calls to Verizon to see if anything can be done so I can be refunded faster as this was a major financial set back for me-I was told no each time. Also, with each phone call to Verizon customer service I ensured that the money would go back to my checking account-I was told each time that it would. I also asked and was informed that it was notated on my account that I wanted the refund to go back to my checking account. On July 5, 2022 my new billing cycle started, July 6, $549.96 was credited to my Verizon account, however, instead of returning the money to my checking account as agreed, Verizon paid my next bill early without my consent, and still did not refund the remainder of the money, $346.23 to my checking account. In fact, on my verizon account now it states that that amount will be applied to yet another future bill. I was told by Verizon customer service that I would have to wait 20 business days for a payment investigation to get my money back. I was willing to accept a partial refund, the $346.23 because my financial situation at one point became so bad. I asked if this could be done on one of my many phone calls to Verizon customer service. I was told by a supervisor that I could go to a corporate store and be issued the remaining funds on my verizon account. He stated he would make notes on my account so that the store clerk would be informed. I went and it was a waste of time, the store manager told me no, refunds like that cannot be issued in store. I have spent hours, many phone calls, and even gas trying to get a refund since 6/20/2022.
