Homechoice and Mbd bad service

I have been trying to resolve an issue with Homechoice but their legal department is never responding,I am being harassed by Mbd people every morning even now as we speak one of them named Nonhlanhla told me that I should have paid my account. I have paid this account on the 2023-05-09 this was my last balance but Mbd is telling me they do not know this account I must call Homechoice now the balance has been accumulating interest which they say I must pay. I have paid this money on the account number they gave me *** but no one seems to be able to assist me, Homechoice call centre cannot help me because they legal department phone lines have been down and on the other hand the interest is going up because Mbd calls me 5 times a day and they are very rude whereas Homechoice cannot help me. Now I have to pay R1000 ,my question is what happens to the R650 I have paid ? I have even asked to speak to the manager at the Homechoice call centre but they always say we will ask the manager to call me back it never happens. Can someone at Homechoice assist me because Mbd are just ******,I will never ever buy at Homechoice because of the bad service ,Mbd I don't even want to talk about them they are rude and unprofessional. They do not know how to deal with clients I feel sorry for the companies that are using Mbd they will lose clients in the future.
