Unacceptable, beyond furious & GATVOL

Very disappointed. Cant complain about service becaise there is No service at all. My mother which is disabled bought a Sinotec Netflix LeD smart Tv at game a few months ago sonce she got it she was able to watch netflix for a few weeks then it stopped. We phoned netflix they say the problem is not by them and that we should contact manufacturers so we tried contacting them they gave my mom a ticket number and been months and still not a peep feedback. We took the tv back to game and damage it a bit because the guy that help us curry it from our car pushed the tv in a trolley which was also a useless trip because they gave us a form to complete to send to Sinotec so that they can send out a tech guy over so we did that and still nadda is happening so now I phoned sinotec 14:30pm on a monday afternoon just to find the recording on their land line which says "you have reach outside our office hours which is 08:30-16:30. This is unacceptable and not fair to my mom its just plain evil
