No Delivery of order

Order a tablet from MTN about a month ago, it's been paid for.<br> <br> I have a reference number, but i cannot track the package, it has not been delivered and I have not recieved any feedback from them and cannot get hold of anyone to speak to.<br> <br> I AM TICKED OFF!!<br> I want my tablet or my money back, and i will move to a new network like Vodacom. Im sure they will appreciate my money a bit more.
