Treated unfairly

I was treated unfairly I bought a TV last year woke up one morning the TV was not working I took it back as it was still under warranty they kept my TV for almost 2 weeks when I call for follow up I was told that the supplier was still busy after 2 days they called and say they denied to fix my tv as it was physically demage at that time the demage was inside, non of metal or scratches on the TV itself to support their statement. I took the matter with their customer service the feedback from them they told me about their loss their buyer of which it got nothing to do with me..I would never buy any appliances at that store they don't care about their customers they only worry about their loss knowing exactly that their product quality is not on standard and yet they will blame it to the customer.
