Truworths don’t treat their customers fairly (TCF)

I have had an account with Truworths for more than 10 years . Early this year I got an sms from Truworths stating that a purchase was made , I immediately called their call centre to report the ***** and I was told my account was blocked , after a few minutes of speaking to their call centre I got another SMS about another purchase that was made after I had reported the ***** , again I had to call the call centre , they now promised that the account was blocked and gave me a password I would have to use going forward when making any purchases. The ***** case resulted in me having to flag my identity number , now I can’t open an account or get any loan without producing a certain letter cause I was scared the culprit might have my I’d number and try to take out other loans. Fast forward to 13/10/2023 I went to one of their stores to make a purchase I produced my identity book when I got to the till, the lady that was helping me called the call centre for verification purposes understandably so, the lady that I was speaking to at the call centre was very rude and was asking me questions that are not applicable to me and when I told her it doesn’t apply to me she said I need to choose one option, how do I do that I asked her ? If it doesn’t apply to me ? she proceeded and said I had failed verification, I asked to speak to a manager cause I felt I wasn’t treated unfairly, I was made to feel like I was interrogated when they failed to do that with the person that de*****ed my account. The manager also gave me a run around, I asked him to confirm how much was outstanding to close the account, he **** and said he can’t see that info , the lady at the shop advised that they can see that information from their side .Their service is pathetic and they don’t know how to speak to customers, the only thing they know how to do is to enable ********s to make purchases from our accounts.
