DPP callback!!! DSTV

On the 1st of March I smsed DPP to 32444 and received an sms back saying that someone will get back to me within 48 - 72 hours it now the 5th of March and still have not received a call from a agent. I have phoned dstv and spoken to 3 different people regarding this and they have done a internal request as well for someone to phone me regarding the special but still have now received a call. Yesterday I told a friend about the special and she received a call back within 15mins of her sms!! The lady she spoke to said that she would phone me at half past 8 today and took my ID and cell no. I have still not heard anything! My current decoder has broken so am sitting with no DSTV but still have to pay and nobody phones for me to organise to sort this out. I feel like cancelling my contract that I have had for over 12 years if this is the kind of services that DSTV gives. If there is a reason for now allowing the upgrade why am I not given a call to tell me???!!<br>
