MTN a horrible experience with my contract

Why does MTN offer deals when they cant deliver on their promise to provide yet consumers are expected pay when payment is due. I took out a galaxy note ultra contract which comes with a free TV and voucher which is to the value of R5000.00 I did not get a voucher nor did I get a TV. The best part is when I emailed you about this I got told you were busy with this its almost 3 months later. Thank the good Lord for the Western Cape Consumer Protector I will get what is owed to me.
