Poor Customer Service

I currently have a Hisense 40'' TV which just recently went black, You can still see some snowing in the background but the screen is black. I made contact with the Hisense Customer Care centre(which in its own is a nightmare) because one can never get through.....anyway, The CC agent confirmed with me via email in the week that the Cape Town Service centre in Milnerton is operating on a Saturday from 9am till 2pm. So I drive all the way out of Hout bay and arrive at the centre at 08h45 with 2 other customers who also rocked up that time, we then waited till 10h50 and still NO doors opening. I then left because I felt it was a total waste of my time and fuel, in fact I would really like to know who is responsible for this poor level of service. I am sure the other 2 customers also turned away eventually. I just don't understand how a Global Brand like Hisense could offer this poor service, Its enough that service standards in Cape Town Sucks but it doesn't mean than a giant firm like Hisense should also conform to these poor standards...….and what is even more frustrating was that for that entire period I was waiting, the Customer Care number was unavailable(just ringing) as well as the store's number...……..I am a very unhappy customer...Bradley ***
