Thanks, Elector, I will try taking it up with my bank. The reason why I have the other person's account history and payment information is that he is my soon-to-be-ex-husband. I used to pay his bills, even though we live separately. I opened his Verizon bill after my payment went astray. Truth be told, I am not optimistic about my bank helping me in this issue. After all, why should they lose money when Verizon is the debtor?
By rights, Verizon should credit me the amount that they mistaken applied to someone else's account. I am a good customer and a long-term customer, though I will not remain so if they continue to make refund promises that they fail to keep.
