Poor service from Hi Sense and Takealot

Still trying to get Hi Sense to fix or refund my TV. Ruben Ruiters is supposed to sort it out as he is their techie team.leader. he returned my 1st mail and subsequently nothing happens. I returned the tv via the Takealot channel and they are more hopeless as they refused tovrefund or repair because the warranty seal had been broken by the hi sense techie when he checjed the speakers. He aso stuffed up the Internet Interface... I am in the middle of 2 companies not taking responsibility for the junk they produce/sell
