ON AIR TV PRODUCT SOLD BUT NOT INSTALLED

I received my Explora in June and called in to have an installer allocated to me, they gave me a contact number of a private individual *** and after several calls to ON AIR TV have not been able to get the Explora installed, the excuse now is that DSTV are busy with upgrades but when I called DSTV they said that they were finished with their upgrades, I am at the point where I want to cancel this contract and go to DSTV directly
