Immensely disappointed in Samsung SA!

Bought a Samsung 60\ plasma TV and other items on 2013-08-09 with extended guarantee, my first instalment was on 2013-11-01 and will end 2016-04-30. 4 months ago the tv became problematic, only switch on after 30 mins, green lines appeared, last week Friday 2016-01-29 the tv went completely black, only sound but NO visual. Phoned Samsung SA, they referred me to their service centre \"FaxSure\" and told me the tv is no longer under warranty and cant assist me. I phoned their service centre and explained, the 1st guy told me the call out fee is R295 and will his technician to inspect the tv and quote me free of charge. The next day another guy phoned and asked me what the problem was, I again explained, he told me he will speak to Samsung, because the tv is only 3 months over its warranty maybe they can assist. The following day I receive a quotation from FaxSure to the value of R10882-44, really how do they expect me to pay that much for repairs, I can just go and buy a new tv for that amount. It's almost like these equipment are designed to break right after their warranty expires. In fact I am still paying for defective goods, disgusting! WONT EVER BUY FROM ****SUNG AGAIN!"
