No Delivery

I ordered a DSTV Explora on the 9th February 2015 and they completed my credit check on the 10th February 2015. Multichoice informed me that the Explora was supposed to be delivered by On the Dot Couriers within 5 to 7 days.Today is the 23rd February 2015 and I still did not received my Explora. I contacted (On the Dot Couriers) and they said that they do not have any reference for a delivery in my name or Multi Choice account number. After numerous phone calls to Multi Choice, they keep on escalating the problem but nothing happens and I had no feedback on CASE NUMBER : ***. I am sure they will deduct the debit order by the end of the month, without me receiving my Explora. PLEASE HELP !!!!!!
