Poor customer service

In 2019 i bought smart tv Hisense 42" at Southgate branch... 2020 the tv started to give me problem i took it back to hifi corporation Southgate the lady who was helping me was Noma after 2months I received message stating that they won't be able to fix my tv because the internal damage caused by ****roach and it was my fault i went the after work. Noma at first give bad service because her attitude was very bad and I asked for manager he then came after 30mina of me waiting for him and I guess he was already briefed by Noma because he's attitude too was something else he told me something that they won't be able to fix the tv... He then said he'll try again to convince Hisense to fix the tv on alower amount because Hisense was demanding R3000 in order for them to fix the Tv.. Even today they haven't call me... Poor customer service
