LCD Samsung TV

Tv disappeared the picture and we called Samsung on 12/12/17 after several attempts because no1 wanted to help us. Technicians only came 14/12/17 to check the tv without spares and they told us that they are going to log a job card, they will be back on 18/12/17 which they never did and not to mention to call and let us know they nologer coming. 0n the 20/12/17 my wife received a missed call from Samsung around 16:35 Due to she was driving. 21/12/17 we went the same boring,airtime consumption route of holding on the phone to be helped and at the end we've been told that our job card has been cancelled due to not answering the one missed call they did on the 20/12/17 , to be help they have to re-open the job card and they can only come to help us between ***. Their treatment to customers are up to bull and its my last time buying Samsung product.
