Disgusting waiting and paying for no service

I received delivery of the DSTV ultra decoder on 20 February. At the time of the purchase, I was told that the installation is part of the package and that Multichoice will arrange with the installer and that the installer will contact me soon after delivery. Having waited approximtely three weeks without being contacted by the installer, I phoned Multichoice on 11 March at around 14h00 and spoke to Thabo reference number ***9 who was very arrogant and said that I should contact the installer but he did not give me the contact details of the installer that I should contact. I phoned Multichoice again on 11 March at around 19h00 and spoke to Zandile reference number ***9i300 who was more helpful. She said Multichoice should be contacting the installer and that the installer will contact me. I also enquired if I can cancel my subscriptions until the installation is done. She said that cancellation can only be effected from the end of the month. It id not acceptable to wait for service and still pay for non delivery of service.
