DSTV R899 deal

I have phoned in about 6 times plus smsed about 4 times with no luck. Once a lady from the call centre phoned me I was busy and she promised to phone me back in 1 hours time I am waiting till today and it is 2 weeks later. Every time I phone I get told they will escalate it with no luck. And that department that deals with the R899 special do not have a direct number. I am not happy been a client of them over 10 years service is very very bad.
