Bad service

I bought a fridge for my daughter on 22/03/2020. She moved into her new place on the following Thursday, the day before lock down. When she plugged it in the fridge did not work but the bottom freezer section worked. Because of the lock down, she could not get it sorted. Two weeks ago we went to Pick n Pay to find out if they can fetch the fridge and give us a new one. I did not want it to go in for repairs because it did not break, it just did not work properly. we were told we can do that but because of them having no delivery vehicles it was a problem. They also never had stock of that fridge. Today she took the fridge back to them with the intention of getting the money back and going somewhere else to buy a fridge. they refused and said it has to go in for repairs. as a result we still have the broken fridge. The person she spoke to was Jabulani. my son in law did get upset and swore at them etc., for which I do apologize. I phoned them just before twelve and left a message for Jabulani to phone me, which she still has not. She has two small kids and has not been able to keep perishable stuff for over two months. if it goes in for repairs it is going to take another few weeks. How can you repair it if it never worked? I would like to get this sorted out as soon as possible. I have always supported PnP above other supermarkets, but after this, I will have to buy my stuff somewhere else. They were most unhelpful.
