This caused my bank account to become negative and not only was I out of twice the money, but my bank charged me an overdraft fee.

I called Verizon Visa and I spoke with a supervisor who told me it would take two weeks for an investigation before they would refund my money.

I am confused because it did not take two weeks to remove my money so why would it take two weeks to refund it?

Their customer service was not helpful at all. I was basically told, "oh well, your account is negative due to our mistake, but you will have just wait two weeks for an investigation."

Verizon Visa has proven to me that they can care less about their customers and all that matter is Verizon Visa getting its payments --- even if they have to remove the payment twice.
