lack of communication from accredited installer

on the 30th of December i app**** for the Explora decoder from Multi choice on their 24 month contract special. i was happy with their service and everything, and it was delivered on the 5th of January 2016. now my challenge is that, i am in the Theresa park, Akasia pretoria north area, and am struggling to find an installer. the one on the list they gave me, does not respond to my messages, and i spoke to him and he said that i must send him my address and i did. i spoke to him again this morning trying to find out if he will be able to help but to no avail, he just does not communicate back at all. i called multi choice to find out if i can use the one i normally use, but i am not getting any help at all. now what should i do with all this equipment i have and i am being billed for two accounts already because i can not close the one that is currently running, and the explora one is already being billed??? please multichoice respond and help me out. i am going back to work next week and am not working in gauteng, which will be very difficult once i go back to work. please help
