Very unprofessional and unpleasant service

purchased a TV from game stores, Liberty mall on the 2nd march 2025 at 2.23pm. When I got home the TV seemed to be working until later that same day the screen went black. I put it straight back into the box and the next morning I took it to game stores. They said they were going to book the TV in and even stated on the repair agreement that there was no damage to the TV. A few days had passed and they contacted me to tell me the screen was cracked and they cannot do anything , I requested a hisence report and they denied. They then told me to come in a collect my broken tv. I asked how that happened because the TV was not damaged when I booked it in and I cannot just collect a broken tv that I had just purchased and not even used for a day. They then told me it was my word against theirs. I tried contacting the customer service manager as well as the store manager and no one cared to help me. I was up and down to the store for almost a week seeking assistance. Each time I had to wait an almost half hour before been assisted. Please help.
