Unisa study material not being delivered

I got this sms on 21 January bill 2016: UNPE***0 was dispatched 4rm Unisa 4 delivery within 6 days - 4 enquiries [URL Removed] or 0800-212-783.<br> <br> It now says on the system that the parcel have a bad address? ??? Why is nobody phoning me to confirm my address? ?? I need the study material as on yesterday. Now it's being sent back to Unisa who is even more useless. Please find that parcel and get back to me ASAP. I want this parcel before the end of the week. Nobody bothered to call me to confirm my address. Please fix this immediately. I need this study material! !!
