Samsung wont refund me for faulty TV!!!

I bought 2 Samsung 32" smart TVs from Game store in Nov/Dec. The 1 TV connects ON and OFF from the WIFI. It’s a struggle for us to connect it to the router that is located right next to it. The other TV is perfect never given us a problem. I took it back to Game and it was booked in, it came back after a month and it worked for 2 days them would not connect again. We struggle to get it on the WIFI, once we do it disconnects after an hour or so. This morning I went back to Game and was sent from pillar to post on what I should do. This is tiring I spent 3 hours at the store and I was never given positive feedback about my TV. Now Game called Samsung and they want to book it in again!! It’s ridiculous as I paid for that TV and expect to get good service from it. I’m not getting any joy from all of this, my time and petrol going back and forth. That TV has a technical problem and Game is not assisting me with that!! Why is the other TV not giving Problems?? I can’t spend so much money and be this miserable! surely I have consumer rights? Samsung and Game are bullying me as a consumer and it’s not right. The products we buy should be at full satisfaction!!
