Faulty goods and bad service

Hi-fi corp and/or came and took my TV in for repairs about two weeks ago, a tv set that I bought new from HI-fi corp not more than 6 months ago. The technicians told me they knew what the problem with my tv that its only the ON/OFF switch that they need to replace and they need to take it in to their warehouse. After not hearing anything from the two companies I decided to do my own follow ups but I was told they just order the switch which to me it didnt make sense as Its been two weeks why was the switch only ordered as when they took the tv set they knew exactly what was the problem with it. Each time you contact panaserve you referred to this call centre without a clear explanation as to why. The call centre will make promises to callback or mail back but they never do, they can never give you a solid answer all they do or say is "we will escalate or we will request for the process to be sped up" but I promise you will be the one that will pick up the phone the next time to call them . A lot of Airtime and data wasted on these companies... What a **** service I got from these 3 companies. You must just stay away from Hi-Fi corp as they sell faulty products, I have never seen a store with a long queue of returns and complaints like Hi-fi corp Southgate.
