Appalling accounts department

Good day. I want to complain about the appalling service at the accounts, department and Sportscene at Carlton Centre for the credit limit on my account. It was on the 19th of August when I googled for the nearest Foschini close to me and Google said Carlton Centre I then went to Carlton Centre and to my surprise there was no Foschini there in its place was Sportscene I informed the guy who was at the door that I would like to apply for credit limit increase. He said it was not a problem they can assist me, the application form was filled in and the documents were submitted. I then called the call Centre multiple times and I was told the application didn't reach this mail box, I was given the Carlton Centre store number so I could check with them which mail box they used, that store did not answer my calls at all the phone rang endlessly . I then called the customer care again and I was told that the documents were submitted to customer services and they will be forwarded to High value mail box. I have called on the 21st and my documents still hadn't been captured. Now I am not sure if ever they reached the correct mail box. I decided to email high value myself with the required documentation. Then on the 25th I received an sms that my credit top up was unsuccessful because the store was submitted at the wrong store or logo. TFG what game are you playing at. Is Sportscene not part of TFG and 2ndly is it my fault that you have failed to update the internet on the stores that have been closed. You need to do better because I had the worst service ever.
