Bad after sales and no feedback or contact

I am so dissappointed with Mancosa right now and how inefficient they are. There is no one I can get hold of , they dont reply to emails either. I asked for assistance and there is still no one who can get back to me. I had a great 1st year but thats about that only thing, they werent even able to help me choose subjects in 2nd year as a result i had to do a course I didnt want , only because they told me that I need to start from year 1 again. Now in 3rd year when they are meant to be even more available they are not. Please can someone contact me asap? This is just not okay , I have paid R34K for this year ?
