Faulty fridge

I am very frustrated. I bought a fridge online and the day of delivery after turning the fridge on, it did not cool. Essentially the fridge is not working. Now I’m contacting Game to give me a full refund for my purchase since the fridge has been sitting in my house not working. I asked for a new one but nobody is coming to fetch this faulty fridge. Firstly I’m told I have to put the fridge back into the box. Now I’m being told that a technician needs to look at the fridge. The fridge didn’t work from day 1, why the hell must I struggle with them after I paid fully for a working fridge. It’s within my rights to get a new fridge since their fridge never worked. I’m definitely contacting my legal team now. This is utter nonsense
