Lewis stores Fix this mess

In November I went to the Westgate Mitchell’s plain store to open an account because I needed a fridge, the sale was successful however not done properly and vital info was missed which I did not know at the time. The initial agreement was that the first Debit order will go of early because in December we get paid early and normally that was the pay date and there after it will be month end until then my employer changed this and the first debit order wasn’t successful however I made sure I got to the store to make a payment however the agreement was breached, the following month the Direct debit went off on the same date, I called the store that they had made a mistake and that as per payslip and every doc provided it proves that I only get paid the last day of the month, I was then told that this has been fixed however it wasn’t because the following month the same happened . I then took it upon myself to just go to the store and speak to the manager about this (Phillip) who then apologized and assured me that it was changed and the consultant looked me straight into my eyes that this has been fixed, mind you I have a Cheque account and every failed DD on my account minimizes my chance of getting a car,home and any loans. The following month the same thing happened and whenever I went to the store month end to make a payment I was told I’m sorry and that they don’t know how that might have happened with no explaination. I’ve asked for proof of this no one is giving me tangible information and now I’m getting messages that I have been handed over to debt collection companies when I pay the account monthly since I got it but because of the DD fault on their end my credit score is a mess, I get calls everyday from the debt collection company …the manager Phillip promised to call me back and have this investigated until today I have been waiting on that call, today the 15/05/2024 I went to the store he had nothing to tell me than I’m sorry, no actions taken to fix the problem than telling me that the girl who messed up my account is no longer employed there, how is all this my fault I don’t wanna know who was fired for what I want this fixed because I’m working on my credit score so that I can be able to get a home and now my chances of doing that are slim because of your companies incompetence and lack of customer centricity. I got a pathetic service from Lewis store / group and to be honest for a company that has existed for years I’m disappointed. To top all this up the store calls me constantly even after making payments which are not recognized by the system to threaten that they will be coming to my home to take their stuff back, calling my friends and family giving them my information and personal information…..does your stuff know what the POPIA act is? I doubt. I know my rights as a consumer Lewis Stores
