failure to respond to requests to cancel request to deactivate system

I agreed to a price lock agreement. I was told that Explora will be delivered. System was delivered to wrong address. They activated the system on the 03/2/2017 without consulting me (I requested for the system to be deactivated) I have made request since 04th December as I have not seen the Explora. I have made multiple visits to the N1 store and made numerous phone calls requesting for the system to be deactivated. They confirmed that the system was delivered to the wrong address. I get told by the call center and the N1 store that they will get back to me. I even sent a affidavit to indicate that I have not received the decoder. On the 19th I gave an instruction for the contract to be cancelled due to the poor response and commitment (reference ********** .) On the 21st when I called it had not been cancelled This morning I checked again it had not been cancelled.
