BAD service with connect FS and the furniture store

customer service is bad. i made arrangement in November for the company to debit outstanding balance so that my account can be closed. someone didn't do her job properly. in December my account was debited twice. I have asked for a refund. i was struggling to get through to customer service. some consultants were answering phone and hanging up. i tried to call for more than 5 times. when consultant answered she said a call for refund wasnt logged. two prev consultants confirmed that call was logged they are not sure as to why is my refund not done. this is bad bad service. i want my refund including the interests that they charged me bcz i was under the impression that my account was closed.
