Very dissatisfied Customer

on about June 2024 we bought a Hisense TV 65inch from bradlows, within 6 months in November 2024, the TV just went quiet - no picture no sound, we took it back to bradlows & it took about 3 months for them to give it back, within that time frame there were no updates from them to advise what is the issue & when I can receive the TV back, I was the only who kept phoning and was constantly told to enquire with Hisense since this is their product, bradlows is not the manufacture which didn't make sense to me, they were suppose to liaise with their supplier (Hisense) and update me since I had purchased the TV from their shop. when they eventually told me to come & collect the TV, the salesperson turned it on to show the Hisense Logo then said you see it comes on, I was happy & went home - when I got home to my surprise, I turned on the TV it showed the Hisense logo then showed a blurry picture, I was confused went back to bradlows but was now I was told it was my fault, I'm the one who caused the issue, I have contacted their head office multiple times however there was no assistance, not even willingness to try to resolve the issue - To date they have kept my TV, My money - so I just wasted my time & money to be exploited by this shop and I have been their customer for years.
