Extremely poor customer service

A month ago I purchased a voucher from the ebucks store using my credit card.. After realising i did not get the discount, I called to cancel the voucher. This was on the 27 Jan. I was told that the refund would be done in 48hours. Its now nearly a month later and I have not received my refund nor communication on when to expect it. Everytime i call i have to repeat the entire story again and hear the same story but my money never gets refunded. It is so disappointing and gives a terrible name to FNB and ebucks. I will continue to discourage friends and family to join ebucks as it has a bunch of fools working for them and they literally come up with every excuse not to pay you back.
