I paid cash but I get statements showing arrears

I bought goods for cash on the 06/11/2014 and 01/12/2014 but to my surprise, I receive statements from Homechoice that I am owing 772.84 in my account. What's annoying is that every time I call customer centre for assistance to get clarity on this account, I am told that it will get fixed to date nothing has been done. I called again today and spoke to a very rude lady by the name of Alin Viner who transferred from one department to the other because she could not resolve my query. Its very frustrating because my credit records <br> gets affected as a defaulter, please fix this mess that you created. Asseblief tog!!!<br> <br> Regards,<br> Tseleng
