Defy fridge bought from Game Online

I bought a Defy fridge from Game Online, which was delivered to my apartment on 2 December 2018. By 14 January 2019, the fridge broke and I phoned Game to assist with looking in to the issue, as the fridge is still under warranty. When they did not assist, I phoned Defy directly to sent a technician to look at the fridge. the technician came on 18 January 2019 and concluded that it is too broken to be fixed. Since then, I have been trying to get a refund from Game, phoning them every day, who has has said that they are escalting thi issue to head office. Defy indicated that they will assist with a refund, but there is no email address to contact Defy, and they are not communicating with Game, so I am still waiting for this issue to be resolved.
