b. From April 1 to 30, 2008, I used my credit card for total nine payments. Out of those nine payments I made, three of them were approved via telephone by your bank. However I received my latest bank statement and was surprised to see that I was charged $ 100 as interests of using overdraft credit. This is totally unacceptable because I was not advised in advance nor my payments been rejected.

a.
Satisfied shall mean the customers are already happy and pleased, it is clumsy to put these words together.
Refund shall mean money back , what is the point to put credit together with refund, it is clumsy again. I even can't understand what shall it mean to arrange for surrogate ?
