Over 3 weeks and 15+ calls, still waiting

I sent Multichoice/DSTV an SMS as this is what is required to get the new Explora decoder deal on 26 June 2015. They phoned back within an hour and we followed the sales process. At the end of the call, after I gave all my details and financial detail, the consultant said that he could not see a result on screen and that he will call me back. I waited until 7 July before again sending them an SMS (I've checked on their site if there was a number I could call, but only found one for technical queries). Again they phoned back and after explaining that I've gone through all the questions before and only need an answer, the consultant escalated to her supervisor. I am still waiting on the supervisor to call me back with an answer. I send another SMS on 15 July, and got a call back but with no resolution. Subsequently I was called 11 times on the 15th by the consultants trying to sell the product to me and each time I had to ask if he/she was a supervisor because I am waiting on feedback. On the last call I asked if I could go into a branch or distributor to get the decoder directly but was informed that I could only get this deal via their call centre. Here I am, still waiting!!!
