Poor service and useless product!

We bought a JVC Smart TV (4K) in June 2019 from House & Home Cape Gate. As we only got married at the end of June, we only started making use of this unit then. The TV is preloaded with applications so we naturally had wifi installed so we could access these applications on our new TV. We have ever since been experiencing numerous problems with the unit. There are times the unit would not switch on or just black out while we are watching something. Some applications will work on a odd occasion and then other days would be non responsive and do nothing at all. The remote and TV seems to be out of sync or the TV Unit does not respond to the remote or some sort of a delay. Firstly a TV is purchased as a form of entertainment especially the one we purchased, Secondly the TV cannot accommodate the applications which is preloaded on the TV, which means that we are not able to use the Unit for the intention we bought it for. We have approached House and Home Cape Gate and spoken to management which sent the TV unit to the supplier for inspection, when we received the unit back we did not receive any form of written report giving an explanation what was actually done, merely a call giving a brief explanation. We have gone back to the Manager at House & Home Cape Gate and followed up what we can do now as the Unit is still giving the same issues. We have received no response thus far, almost 2 weeks later. So our Unit is now an Ornament in our home! Really disappointed in both House & Home and JVC on the client service and product sold!
