SAMSUNG NOTE TV PROMOTION!!!

So today I just had enough with this company, maybe I get A response after this. I also see my mom is not the only one dealing with the same problem. She took out a contract last year November at MTN and she is still waiting for the tv that was supposed to be part of promotion? I call them almost every week and even up to twice a week and there is always something else. They have everything they asked from my mom but still nothing. I had someone call me the 2 August to say tv is with couriers and will be delivered latest 19 August but still nothing. I called them Monday and lady I spoke to told me it was rejected due to no tv licence and I told them it was sent to them a while ago and every time I call something else is wrong. She told me she will look into it and get back to me end of day. It’s Thursday today and still nothing, tried to call her but apparently her extension does not work, then I told them I want to speak to a manager because I am tired of people never getting back to me. I was on hold for more than 20mins and then decided to hang up. I am really tired of this BAD SERVICE!!!!!! Especially from a company this big.
