Very bad experience Supreme Finances

The worst place to ever borrow money from. I advise people to never ever go there when they are in need of a loan. I borrowed money from Supreme Finance last year, I was very desperate and interest was so high, but I did it anyway and I was supposed to pay back my loan until February 2019. So they started debiting every month with no hassle, they always got money in my account, there was never a problem. Then came February 2019 and I received a call from their office telling me that they made a mistake and that they have been debiting R200 less from the installment and that they apologize and that I still owe R400 more. I told them I don’t have money and that I’m going on maternity leave soon, but they can debit the R400 end of the next month which was March. March came and R400 was taken from my account, I did not have a problem with that. Then I received an sms telling me to come fetch a goodybag, I went to their office and the lady told me that I still owe because they made a mistake on their side. I told her I do not have money because I’m now on maternity leave and not getting a salary anymore, she told me that there was nothing she can do on her side and that I needed to pay up?? I told her that it was not my fault that they made a mistake, money was always in my account. So now I get texts from the head office telling me that I’m in arrears and that they handing me over to their lawyers. I called the head office and spoke to a lady called Virginia and explained the story to her, she advised that I call the branch again and speak to the manager, so I called and the manager rudely told me that she was not there when everything happened and that she cannot assist. I was then transferred to one of the ladies that work there and she was also very rude and told me that she was not the one that made a mistake and asked me who is supposed to pay up the balance. The call continued until she said she will call her area manager and get back to me? This was 3 weeks ago, every time I call in and ask for she says she is busy with a client or they tell me she is not there at all and that she will call me back or a colleague takes my number and tells me she will let her call me back? I’m still waiting. At the moment I’m getting threads that I’m being handed over for something that is completely out of my control and something that was caused by their staff. My account is now not looking good as they always try to debit when there is nothing in my account. Very bad experience from carelessness from the Supreme Finance staff.
