Fault fridge

I did a laybyed fridge and microwave with fairprice kwathema square.. I paid it up in mid January 2021 with hope that I was moving to my house.. circumstances made me not to move in February .Only managed to move in begging of March that's where I have switched the fridge on since it was delivered. The fridge never cooled on and I reported the matter to the store and I was told that I have passed my 7days guarantee period it needs to be repaired. I was not happy but I tried to understand as procedures are different from stores to stores. Manager told me that the technician will be in my house within 72hours in which he did come it was on Tuesday the 8th he told be that I should have switch it from day one on arrival but he will order the part that is faulty. I have explained to him that I bought food that needs to be refrigerated he promised me that it will fixed immediately when the part is received he will come back. I had to make follow up the next Monday the 14th with defy repair center where I was told that the technician was given the replaced part on Friday. The technician only came to fix the fridge on Wednesday the 17th.the following day the fridge have strange sound I called fairprice manager to inform her. We agreed to wait two days to check it will be okay..On Monday after work when I got home the fridge was not working I inform her as I got her number..I have explained to her that am not happy as first I had to give away food that I bought and now the same as it will take time to g it sorted. I called fairprice headoffice on Tuesday trying to get quick solution with no luck. I called defy where I was advised that they will send technician and I must explain my problem as I stated that I no longer want the fridge can the do exchange...on Friday I called fairprice headoffice again and spoke to the gentleman who advise me to request exchange when technician arrives..only receive manager call on Friday to let me know that technician will be coming and she has requested that exchange but it must be assessed first.I ask her to check at what time they will be by my house, later she responded that they will be in my at around four. I had to make means to be home at around 4pm to get this sorted..I even called the technician who came and fixed it first time to ask when will they be in my house he said it's later they will come on Saturday, I was still fine with that. On Saturday the 28th I informed the manager that no one have come to check the fridge. She stated that its early I must give it time. Around 4pm I informed her again she said she will check and get back to me..when she called me she told me that the technician I spoke to he does not have job number and she can only find out on Monday I must arrange for someone to be in the house in case they came..Am in the new place where I know no one and told her I'll ask someone to drop of the fridge in the store and can I have this sorted by Friday...when the guy came to collect the fridge so he can drop it off tomorrow 29th March 2021 I took photos so I won't have any issues only to find that there is dent closer to where the technician fixed. I forward the photos to the manager that I don't want any issues..we were back and forth that it was physical and she said I never reported it..but how can I report something that I have never notice only saw it now when I took photos of the back of the fridge. I have never ever experienced this in my life. where I never used the fridge and now am told it's physical damage.what about what am going through have to give away food in this tough times where every cent count to accommodate their time to come and sort out this issue..i normally buys at fairprice due to their reasonable price and they laybye process but am truly disappointed the way my matter is been handle by both fair price and defy..
