Bad service

Good morning <br> <br> My name is Phindile, I was so excited when they agent call me and told me about they special, I didn't even think twice I order a comfort set... and it was damaged and I had to return it and they told me that unfortunately their don't have stock they will give me a discount in my account which they did. and the sms was sent to me on the 31 December 2015 that my account has been resolved and my balance was R566.01. and on the 5 January 2016 made a payment of R350 but to my surprise when I checked my statement they was another R480.46 interest that was charged. when I ask about it they lady that I spoke to Babalwa told me that they will sort my account and she gave me the ***, I've waiting for 48hrs nothing was done. I kept on calling and promised that my account will be solved till today. my account number is ***.
