I have contacted customer service several times about this, and there doesn't seem to be anything that can be done, the actions are apparently hardwired into the system.
Last month, I changed my auto-pay bank account from one back to another.
After entry, you can only see the last 4 digits of the number put in, and there is no confirmation/check with the bank that you have provided a valid number.
So when auto-pay time rolled around, I got a notice saying that my payment was rejected, and a charge was placed on my account.
If Verizon gives me no way to verify the account number I put in for billing, I do not feel like it is reasonable for them to charge me a fee.
In addition, now my account tells me I can't sign up for autopay again until march or 2021.
After spending 5 hours on the phone with support, and being transferred to numerous people, the best I could get was the $25 fee dropped, I still have to log in and pay the bill manually every month, and lose the autopay discount.
Has anyone else had similar issues?
