Poor to no Communication from NOSA

I recently registered to do my Samtrac E learning modules, I have completed all four courses, yet two of them still shows 50% completed.

My problem is that whenever I try to talk to someone at Nosa, either to find out when i'll receive my course material or more information regarding the course or information as to why my E-Learning isnt showing complete - It's an eternal struggle to get a hold of them. Today alone i've phoned them a total of eight times which they were unable to dispatch me to someone who could assist. I've mailed them - which goes through a helpdesk - NO RESPONSE YET. Absolutely horrid communication!
