Samsung/MTN promotion marketing gimmick

Samsung South Africa delivers poor service and provides no feedback. I have claimed a promotional offer on the 5th of February after meeting all of the prerequisites for a 58" TV only to find out today that I do not qualify for it and this coming after numerous queries to the Samsung care line. The promotion was being run by Samsung in conjunction with MTN. I've always held Samsung electronics in high esteem but after receiving service like this makes 1 consider as to where they loyalties should lie. The disappointing part is that my contract costs me R1869.00 per month and part of the deal was the promotional offer of the TV of which I now supposedly do not qualify for. Big corporations such as Samsung and MTN need to be taken to task for running these marketing gimmick. A client should never need to chase behind a company, feedback/responses should always be prompt I'm this day and age. Very very unprofessional
