Poor Customer Service

Good day I am very unsatisfied with my service from HiFi Corporation Westgate we bought a 55inch Diamond LED TV from them on the 20th of December 2017 we had the TV for 3 months and 8 days when the Television just stop working it simply just wouldn't swith on so I return my TV to the store on the 29th of March 2018 since then I had to phone the store multiple times in seeking answers on the repairs of my TV I am very unhappy with their customer service.
