Confused: 1. Threads say usually must use credit card. I used debit card. 2. During the order, the agent said she was not sure but since the system took the debit card, it is OK. 3. My confirmation says all ok but mentions if debit card was used, it could delay things since they would need to call me. Would this call only be if there was a problem (not enough funds?) ? 4. My debit card shows the charges already have been made. 5, Should I try to change to a credit card now or let it go?
