Overpayment on a closed account

I've been trying to get my refund almost a year now, every time I call the call centre or visiting the branch they always give me a number that I should call ***/9377 and both these numbers are not working, I just need my money back, I did fax through the documents they told me to fax at the branch and until now my money has not being paid back. <br> <br> Why is Edgars doing this to me? I've been a loyal customer for more than 6years and now that the account has been overpaid they giving me problems. <br> <br> \Unhappy customer""""
