Intec Needs to WAKE UP!

I have been trying to contact Intec College via emails and have not got any response. I have emailed every email adress I could find. I need a copy of my diploma I obtained through Intec. There is no numbers to call. No one response to emails. It is just a struggle day after day to get in touch with this place. No wonder half of SA is jobless, everyone is waiting for Intec to write their exams and waiting to get their diplomas/sertificates.
