After sales service and communication is disappointing

I purchased a vehicle from your Springfield Branch a few months back. I paid the additional R3000 for registration and the whole works... It has been a number of months since purchase.so I though I would check in on the Natis website to see if my vehicle is noted in my name, it is not. I sent a follow up email to your customer care @ we buy cars .Co. za (without spaces) to find out what (if anything) I still need to do. No1 week later and no response. Does anyone monitor this email? It was sent on 13 Jan at 11h11.
