Poor to no service Sleepmasters Gugulethu

Three months ago i logged my own complaint for a 65inch tv i bought at sleepmasters gugulethu.I did everything myself to the point where i received my authority number to exchange.With no help from the store manager,i still reached out to him forwarding everything i have done.All he needed to do was arrange with Hisense to collect and deliver the new tv.To my avail nothing happened with stories after stories.When i asked him to speak to his regional manager he told me im welcome to liaise with him myself.I proceeded to email their head office,needless to say 2 weeks later still no reply.I have now reached out to the ombudsman hopefully i will get the necessary help before my warranty expires.
