Poor customer service and return policy

I purchased a Defy Washing machine on 20 June 2022. I took out the extended warranty. On October 17 the machine stopped working and started showing an E13 error. I called Makro customer care and was given a reference number - ***. A Defy technician came out and advised after a few days that there is a problem with the pc board and they will need to order a new one. I told them that to have a problem with the pc board after only 4 months is a huge red flag and that I will return the machine to makro and get a credit so that I can purchase a new different make from Makro. I have since called Makro on 31 October 2022 advising them that I wish to return the machine and get a store credit from makro to purchase a new machine. I was told I will receive a call back from Makro. Makro has still not called me and all follow ups were initiated by myself. I have since called Makro on 3 Nov and 9 November and still have received no assistance. I was given another reference number ***. Makro informed me that they are waiting on Defy to advise whether they will issue me with a credit. My frustration is that I DID NOT purchase that machine from Defy. I purchased it from Makro. Makro has a 6 months credit refund policy besides the fact that there is obviously something very wrong with the product from the manufacturers side because for a pc board to stop working after 4 months is a huge red flag that the product is faulty. I am been given the run around whilst Makro and Defy sort out who is responsible. I don't actually care what arrangements are made between Makro and Defy. All I care about is that I paid close to R10 000 at Makro and Makro needs to refund my money. This is a major inconvenience for me. I must now wash laundry by hand while I have a washing machine serving no purpose in my home. I am requesting Makro to issue me with my credit. I will drop this machine off at your store in Springfield Park where I purchased it. Makro needs to contact me and get this rectified.
