OK Furniture worst customer services /lack of services

My mother bought a Samsung 49inc TV screen. It wasnt even a year and the tv, had a mark inside and it carried on till the tv didnt work (picture wasnt displaying but sound was owky). So my mother got in touch with the store and the way the matter was handled was total horrible and with poor customer service. Firstly without checking the tv's issue they had already concluded that my mother was at fault (that part shocked me as i am aware that when you buy something with a warranty ,the store you bought it from will have to check the damage before giving any input on the device till the provider checks its fault ) .Anyhow that passed then they didn't want to support my mother with the process of bringing the TV over to them. Eventually when my mother got in touch with them to go check the TV ,they THAN said it was a physical damage which falls out of the warranty. I dispute the process and customer service received. My mother is over 50+ and that TV was mounted on the wall and has been since it came home and my mother has had no body but her use the TV nor would have know if she had damaged it physically. I would never allow any other family member to use OK furniture -WORST SERVICE AND WILL CONTINUE WITH THIS COMPLAINT TILL THAT TV IS FIXED BY THE STORE AS THEY HAVE SNOW FOUL PLAY.
