Unfair treatment

My name is Mildred Babedi, I have always paid well even few rands more every month. Suddenly Jan 2016 no deduction went through and I kept going to the shop to fix the matter but no one was able to assist me. My biggest disappointments occurs when I really needed a skirt and a shirt. 1 at sunny park told me my account is blocked. I have paid the account yet I cannot purchase anything or even do set aside. 2 I ordered a skirt and agreed to pay more for delivery but still I was told my account does show I have paid but they can not process my purchase. 3 when I called the call centre I was told they acknowledge that their systems were experiencing technical problems. I am still waiting for them since I have a event this Saturday 20 Feb. Truworths has failed me. It pains me because I have never been in erreas with them but I cannot get they service I pay for yet they are the once who got me in arrears. Many times I went to different shop trying to understand why they did not deduct to date I am not answered. I feel they deliberately do this to well paying customers so that they can gain more. I am very concerned with my credit score and I feel truworths jeopardising my name and record
