Dissatisfied Customer

I've been a client with Foschini for about 20 years. I paid up my account in May 2018. Yesterday I discovered that Foschini listed me as a default payer to the amount of R32000. I've never had a credit limit of that much how on earth would I have bought for so much. I informed them of this incorrect listing. I was told by the lady (Natasha) in customer service that she can see my account was paid up in May last year but also that I have been listed at the credit bureau as a default payer to the amount of R32000, she can also see that I've never had a credit limi of that much. She will escalate this to her Team Leader / Manager and they will contact me the next day. Next day no contact was made, I had to call them again. Asked to speak to a Manager but was told that she needed to go into a meeting. Is a meeting more important that a client of 20 years. I have made an application at a bank and a clean credit record is need, this has now tarnished my name and held up my process. Bank has given me 3 days to respond, 2 days later and I have not gotten any further with Foschini. Team Leader / Manager refuses to speak to or call client back.
