Game Head office not helpful

I purchased a fridge on Game online and when I received it the courier people had difficulties with fitting it through my door so they took a decision to strip it off from its packaging. When inside the fridge did not fit in my units and I contacted Game the following morning 4 December 2019 to request for an exchange. My case was escalated as I did not have the original package with me since the courier people left with it. 6 days later Game head office decline my request as per the response I received from the consultants. I do not have a fridge to use and I am stuck with a big fridge that does not fit. the courier company refuses to come collect the fridge. I did not purchase this fridge from the courier company why is it my problem if they don't want to come. why is Game not resolving my problem and creating more hassle for me as a customer.
