Explorer order

I contacted DSTV in January to order an explorer under their new offer. It took over a week for someone to call me back to process my order. I was informed that I would be contacted in the next week to organise delivery. After 3 weeks I called DSTV back and they assured me that they elevated my request and gave me the delivery company's number. The delivery company had no record of me. When I called DSTV back they said they could not access my information but that they would get the Explorer department to call me (you cannot contact them directly for some reason, just send an sms which they do not seem to respond to). It has now been over 6 weeks since I initiated this process, and I have no means of contact or follow up. What do I do from here?
