Poor customer care

I called the store to advise them that I would like to change my debit order date. The response I got was I will need to go into the store as the call centre wont be able to assist and this was October2022. I then made an arrangement plan to pay online which I did on Friday as I was now behind with payments and advised that by February I would be back on track. I made a payment on Friday and to my surprise I received a call from my mother advising that there are guys who came to repossess my furniture stating that I am not paying while I made a payment on Friday morning and was going to make another payment on Tuesday. I was so embarrassed to receive a call from my mother who was in a state of shock. The lady who was assisting me advised that he called the guys and advised them to leave my mothers house. Firstly I want to understand that how did this happen when I made payment. I have messages where I even asked the lady (Zama) to send me the banking details and also advised her of my home address. She never came back with feedback in regards to my address being changed to the correct one.
