False Advertising and worst service

I am giving 1 star because there is no zero star. Problem started when i ordered a LEAH 9 piece duvet sets which was advertised as R2799-99 in 2020. I received the duvet set but the when I received the first statement it said R5600. I called to question this but no full explanation was given. I paid a few installments and then after a while of not paying I received a call from Norman and Bisset. I told them what happened but I was still not getting any joy I ended up asking for the settlement amount and they said R6500. I paid the amount in full on 15 August 2022 and I also recieved a paid up letter because I did not want anything to do with Homechoice. Now recently I have calls from CSS attorneys claiming that I am still owing Homechoice. I have tried to call the call centre they tell me I need to call Legal department and their Legal Department never answers their phones it been a whole 6 months and I still cant get hold of them but these attorneys keep send that i need to make a payment arrangement and when I ask how much I am owing and also send the Proof of Payment and Paid up letter they tell me they will attend to the matter and then a week after that the emails start coming in and they start calling me again. This is a **** store and I want nothing to do with them. I want my name removed from the bureau because I have proof that I have paid and I know I have paid. We will discuss the false advertising another day because I have already paid their money and I want them to get off my back.
