Worst service ever....

I was contacted by Multichoice and offered a 24 Months Price Lock Package, that came with free installation..After a few days the Xplora decoder was delivered, and I received no further communication from Multichoice. About two weeks later I contacted them and was given contact details of two installers in my area...I called the installer who did not even take down my details but cut me off and told she will ask an installer to contact me...without taking my details. This is the worst service I have ever received. Since when do I have to be the one making contact with installers? If I didn't contact Multichoice, how was I supposed to know that I was supposed to call...can someone kindly assist.
