BAD CUSTOMER SERVICE

Bought a Hisence tv with them in December and 3 months the line the tv was broken and because of the lockdown I was unable to return it and when I eventually did the store told me that I had to book the tv myself and had to go through the worst service from Hisence as well...Its been 2 months now that I've been doing this and neither the store or Hisence has intervened and this is so frustrating for me as I've been without a tv for 4 months now and I was promised warranty and Guarantee but the service that I am getting it sucks and I'm stuck with a tv that's not working and the worst customer service from Makro crown mines and Hisence.
