DSTV Shoddy customer service.

I recently bought a decoder with free installation and was told by the dealer, HiFi Corporation, Fourways to phone the dstv no on the package. This I did and was told that they do not give installers numbers. After further discussion, the operator agreed to give me an installer's no. I phoned and was informed that they did not do installations as per the offer. There would be an hourly charge. I then thanked them and phoned DStv again. Ultimately I was given another number, which I then phoned. The business turned out to be Multisim installations and I spoke to Bronwin. She was very helpful and arranged for a technician to install on Monday at 9.30. I organised for someone to be at my address on the agreed time. By 10.00am I phoned and the phone was answered by another person, who had no knowledge of the appointment and took all my details down again. Then informed me that Bronwin, who was not available(in a meeting) would call me back at some time in the future, unable to give specifics! The installation would however take place "going forward", but still indeterminate. I am still waiting...... The question is: do DStv actually want to do business and how are their appointed agents trained?
