reel bad serves

I bought a starsat decoder on the 26/08/2015 from OK furniture in Rustenburg, they gave me a number of a installer that i must phone to do the installation of a dish,i phoned him and he told me that he can do the installation on Friday 28/08/2015. on the morning of the 28/08/2015 i phoned the installer and ask him what time is he going to do the installation ,he told me at 15h00 , at 16h00 i phoned him and ask him if he is still coming to do the installation he told me yes, at 17h00 i phoned him again and he told me he can not do the installation cause his signal tester is broken ???. i am a service provider my self ,and it is totally unacceptable to me that a big company like starsat is using installers that s not competent, if it was me i would lose my business. i am already a existing client of starsat and there four i expect from them to send me a competent installer or send me a dish so i can install it myself <br> regards.
