Unresponsive SkyNet

Paid for a license disc renewal at FNB and the delivery service is contracted to SkyNet. On the 10th of December I received the message stating that the parcel is out for delivery. It is now 2 days later and I still do not have my parcel and I have phoned ( you wait forever on the phone and then they just drop the call). Sent 3 emails and have not had any response. What can be done to get in contact with someone that can resolve the problem?
