The call center does not provide any service

Bought a Hisense smart TV with the DSTV now app preinstalled but unable to play live TV. The rep at Pick & Pay Hyper didn't assist with the sale (ironically the Skyworth rep) at all but was quick to ask the slip so that they could get commission. We are assured that all apps worked perfectly. The biggest problem is that I have spent hundreds of Rands calling the call centre over and over again Kevin Mlolomba for Hisense simply has to send a software update via email to me but this is never done.
