Makro Cornubia Service Sucks

I purchased a Hisense 271L Fridge freezer combi from Makro Cornubia in August 2019. The fridge is still under guarantee and now has a problem which cannot be repaired. I was advised that the fridge needs to be replacrd by Makro. Firstly took then a week to actually log a fault for a technician to come out, with me having yo call non stop and fighting with them i eventually am told the fridge i bght was discontinued and they do not have it in stock. They can offer me a smaller fridge. This is utter nonsense, i paid for a 271L fridge and thats what i should be given or something bigger but definitely not something smaller. Obviously as time passes the price of everything has gone up, it cannot be my fault that i paid a certain orice at the time and now you cannor fulfill the terms of replacement. The salesman Marvin at the tome of the sale was great now when its time for after servuce he is giving me the run around and basically rude when i speak to him he just keeps quiet on the call. What kind of staff and customer service is Makro offering. I am absolutely furious, i will not settle for a fridge that is smaller than the one i paid for.
