Games stores bad service

I've purchased a fridge from game online . Received it 28 November 2020. Fridge wasnt cooling, I phoned game maybe 10 times for them to collect ,they only collected the item on the 19th December 2020. Afterwards no one called ,I had to call them regarding what's going on ,then they claim need banking details ,which I sent immediately. Thereafter a consultant called acknowledging they have recieved the bank details and refund be done in 2 to 3days . It's now the 28th December and I still dont have my money back. Called today 28th Devember they claim awaiting item back from courier to refund me . Must a customer wait 1month to be helped on an item that stores food. FOOD which is so expensive .
