Game refuses to refund and replace defective fridge

I purchased a Hisense fridge from Game online on 6 June 2018 (R4000.00) for my mum. It was delivered a few days later to her in Pietermartitzburg.

3 weeks later she noticed that the rubber around the fridge started coming loose. We immediately escalated this to Game (11/7/2018). A technician from Hisense came out to look at the Fridge a few days later. He indicated that it is normal for this to happen and pushed it back in and left. However the rubber continue to come loose and on opening the fridge the rubber pulled away from the door. Contact was made again (20/7/2018) with the Game online team (Reyhana Kadir) highlighting that the problem is persisting. A second Technician was dispatched . The technician indicated that the entire door needed to be replaced. At that point I called the Game customer support and indicated that I would like the fridge to be removed and I will purchase another brand. There was no way we were going to fix a fridge that was less than 2 months old. I got no response from the Game online team to my request. Eventually a third Hisense technician was dispatched who indicated that there is nothing wrong with the fridge. The rubber was still coming loose and pulling away from the door. This lead to incredible frustration. After 3 calls to the Customer support line I managed to speak to Kirk de Fries (Game online) who promised to speak to Hisense and get the technician reports. He indicated that the technicians said that there was nothing wrong with the fridge. I asked him to send them to me which hasn’t been forthcoming. At this stage I protested and said that I refuse to keep a defective product. I asked him to please take the fridge away and I will have it replaced with another brand from Game. He indicated that he will escalate this to his manager and get back to me. A month went by and I did not hear back from him. After calling him last week, he has now indicated that a fourth Electrician needs to come out to assess the fridge. I bought this product from Game. The after purchase service has been nothing less than shocking and disappointing. I am their customer and it seems like they refuse to do the right thing and take back the defective product and refund my money. I am currently at my wits end and I believe that they are going to insist that my mum keep the defective fridge. Please assist.
