Unfair and unprofessional service received with lounge suite retained

My name is Sue Anne Darvel. I bought a lounge suite by bradlows westgate mall, Mitchells plain through a worker named Fuad whom is now deceased. The first one broke a d we called them to fix and collect. They then replaced it with a new one and said if it happened a third time we can change the set. After returning it the second ti.e we found out that the salesman purchased it on his staff account and is deceased. We then spoke to the regional names Paul and he mentioned they cannot credit me, but could replace with a new one. Then the third time we received a new one, different color but with half stuffed pillows as a backing. We then complained immediately not knowing the manager was replaced. When we then followed up with store , we were in the pandemic and they could not collect anything until level 1. Zubaida the current manager then said she would log the call and will explain the situation and prior faults. They collected the suite which the complaint was for the pillows and seat comfortability. The collectors practically dragged the suite out of our home and broke the legs of the suite. We then received s call from the headoffice saying we are held liable to pay the cost for fixing the legs and stuffing of pillows due to guarentee that expired. Our understanding was that the new lounge suite was delivered end of February and a call was logged immediately after receiving it. Now they are refusing to return our messages and emails and they are ignoring our calls. We spoke to current regional manager and warehouse manager Eugene, but none of them are returning our emails. Please assist as we do not know what to do and where to go. Sue Anne Darvel. ***
