Samsung tv gone repairs 5 times and is with Samsung for 9 months.

I bought a Samsung tv in August 2021. In 2022 the tv went faulty and i dropped it of at Samsung (Tm Electronics) and they replaced the panel. 2023 July tv had the same problem again i took it to Samsung and they replaced the panel again. When i took the tv home i noticed the was hair inside the panel. I again dropped the tv off at Samsung. They called me after 2 weeks the tv was ready. I went to fetch the tv and requested they switch the tv on. There was a huge scratch on the panel. The staff fought with each other as to who damaged the unit. I was not happy and requested management to call me. With no response i approached Game and after a 2-month battle i got no joy. On 27th March went back to Samsung for the 5th time to collect my tv. Upon switching the tv on it only showed half picture the staff assured me the tv will be repaired and delivered to my house in 3 days. It is now 15days and not even a call. I want my money back and no longer will to accept a tv that was repaired 5 times.
