SkyNet has my License discs!

I ordered and paid for my Car and 2 trailer license discs through Natis in late November and on Friday 29 November got a message to say my documents were on their way and would be with me in 3-5 working days. Strange, since I usually get my licenses in 2-3 days from renewing. Well, today is the 9th December and not sign of a delivery. When I call SkyNet, there messages assure me that my call is valuable to them, and that I am going through to an operator, but I have never spoken to anyone. My tracking ends with my licenses at the Durban depot on 29th November. I have no idea what to do, will Sky Net pay my fine when Metro Police see my disc has expired? What is Natis responsibility in this? Has SkyNet liquidated quietly or has Natis not paid them, so our discs are being held ransom? Unfortunately customers are in the dark, they have our money and discs and we have no way of getting help.
