Faulty TV and Worst service

Monday 19 September 2022, (Yesterday) After 2 weeks of begging for a new TV and them refusing. I went to ask for my Money back at the store, now because I want my money back they suddenly want to offer me a new TV and the manager Jimmy said to me it's a favour and that's not how they do things.You don't take customers seriously and I find it very disrespectful that you would say to a customer it's a favour, how is it a favour if my money is spent to buy a TV and it's faulty. I have been at the store returning this TV 3 times for the same problem, I am spending my money to go to the store. Yet I am told it's a favour.
