Milpark unfaithful

Just doing my advanced certificate at Milpark distance learning im experience difficulties regarding with everything i always called studentservice but no answer ,my log in sudents pass word is no longer working its seem like someone lock out me ,i asked assistant fr them via email but no help its been almost two months now.they told me all activities test and assignments do contribute with 30% in final mark but it seem like they is no such coz some of my marks is 29% yet i did do assignments and test and they don't show you how do they mark it .and im very disappointed because i was so bold with that modules. I call them and ask them to re mark my paper coz i feel like something fishing but when she was checking she hang up on me and she never call me back .Im so disappointed Milpark promise that as a distance learning they will never leave me alone but now im alone ,not even the mansion a huge money i paid for those modules no explanation nothing.
