A) 10 days

B) 5 to 10 days

C) 2 billing cycles

D) 7 days

The correct option is D.

When one overpaid her credit card bill and request for refund, the overpaid amount must be return unto her within seven business days. This is one of the rules that were put in place by Federal Reserve Board. The rule, which is also called Regulation Z requires all lenders to declare the terms of their loans.
