TV fault again

Bought a lg 65 smart tv in December 2017. Had it repaired in December 2018 now again it has the same problem. It will.be out of warranty this December and LG say that is over 6 months after the first repair and it has to be repaired 3 times before they change the tv. I am still paying for this tv on HP which is R20000 + my intrest over 36 months. So this is just frustrating because I want my tv replaced as this is not a new fault it's the same one. So I expect the store to sort this out please.
