GAME - terrible customer service, fighting for refund even after Hisense confirmed fridge needs upliftment for credit

I will never purchase from Game again. Bought a fridge on 6 July, had it delivered on 13 July. It was defective by 27 July which I reported by email and phone. I have had a Hisense technician come out to comfirm this and who has sent a report to GAME confirming this and sending an upliftment and credit jobcard. My Consumer rights are that I get a refund but it is now a month later and GAME have yet to respond to my emails, and collect the fridge or respond to any emails. Every time I phone customer service I get told a different story and some of the people are so rude I have no idea how they are in this department. I will be taking this to the ombudsman, it is shocking service.
