Already fed up and I haven't received my study material yet

I am deeply disapointed in the service I have received from Milpark since the beginning of my admission. When I app**** for my admission to Milpark I had to literally phone (and when you phone you phone 3-4 times and the phone just keeps on ringing for more than 10 minutes) or send an email each and everythime to follow up on the progress of my admission, only to find out that they required more documents, I asked them why I was not informed of this, this is causing a delay, they could not answer me and only apologised EVENTUALLY I got approved, then I registered for my 1st 3 subjects, again I had to follow up each time, and this time they said it's too much work to do on the same date I need to split my subjects again I asked why wasnt this brought to my attention earlier causing yet another delay in my studies the system was offline for maintenance was the excuse this time causing yet another delay. When I initially enquired about the course I am taking (FET Certificate in HR) they informed me that I do not need to purchase any additional handbooks that Milpark will supply everything, upon registering for the business envirnmonent subject prompted me that I need to purchase an additional handbook for this subject? I sent Milpark an email enquiring about this, they informed me that it was a recent system change, okay fine I will accept that it is for my education after all. FINALLY this week I got my sms's confirming my registrations, when I logged into my student portal/courses my business environment does not show and its my 1 subject that is due, I tried phoning twice each time the phone just keeps on ringing for more than 10 minutes then I decide to hang up, again this morning I tried to phone no answer, I sent an email yesterday having to wait more than 48 hours for a reply for urgent enquiries to me its unacceptable. I chose Milpark because I 've only heard bad things about UNISA. I haven't received my study material yet and I am already fed up with the patethetic service I have received with Milpark. Why do you offer telephone support if no one answers the phone?? I am new to the studying through the post and if I do not understand certian things I apologize but i atleast expect a call centre to pick up the phone and assist to the best of their abillity. I am extremely frustrated, irretated and fed up. I feel that I have not received any level of good service. Can someone please get in contact with me urgently my student number is MI **********
