No customer service at all

Game ( Mass Stores) carnival mall.

I bought a JVC smart TV and took and extended warranty with the TV, the sales person that was helping wrote the wrong the details on my warranty document, my TV has been giving issues so i took it back to the store knowing that the TV is under warranty Game books the TV in telling me that they will fix it - there has been no communication from anyone at game to let me know when will i receive the tv or what is the problem i phoned the store for the past 5 weeks to find out what is the matter. spoke to a manager by the name of Zwele who does not communicate at all every time i phoned no one could assist me, i finally got hold of a manager by the name of Adelaide who assisted me 5 weeks later , they told me the TV is ready on 16th of march as i booked in the tv in the first week of feb,so i go and fetch the TV and the problem is still the same , when i go back to the store they tell me unfortunately our consultant made a mistake on the warranty document and my tv is no longer under warranty. @Game you staff are not customer centric at all and the service is really perthitic
