No feedback at all!!

Can someone call me back so I can cancel my studies and be refunded? I left 2 complaints already, for which I am phoned back each time by Tyrone. He told me to only send a message with my queries to ***. The first e-mail I sent was on the 23th March 2015. According to what I understand, I should receive feedback within 48 hours. On the 2nd of April 2015, still no feedback. So I phoned once again only to be told by Mickaylah that she confirmed with Palesa that they received no e-mail from me on that day. I forwarded it to Mickaylah on her request, and she told me it is the long Easter weekend, so she will get back to me by the Tuesday, 7 April 2015. 13 April 2015 still nothing, I even sent I follow up e-mail, still nothing... I phoned again on 14 April 2015. I spoke to Dewali, and he assured me that he will help me, and he doesn't know why his colleagues are like that and not getting back to me. Guess what, 2 days later and still NOTHING!!! I am FED-UP!! This is the worst service ever, what does it help to pay so much money for nothing?? So I would like to have it paid back and cancel with Damelin, because I am not struggling on like this anymore.
