Bad service at Intec, not giving right procedures

I enrolled with Intec in 2014 to write in 2015. I phoned the student consultant, I told him that its not possible for me to write will it be a problem if I write in 2016, he said to me it wont be problem, instead of telling me the right procedures. I kept in contact with him on a regular basis, to make sure. I wanted to register last year to write this year, but the school requested a extention of registration letter. I couldn't supply the school with the letter as Intec doesn't want to assist me, they keep on saying my course expired and I could've asked for an extention letter before the examination, but once again the student consultant didn't give me the right procedures to follow. This morning Intec phoned me, saying that I have to phone the Dept. Of Education and ask them if they will assist but they cant promise anything and that I have to write this year June July, 6 subjects 3 papers per subject. How is this possible to do this in 5 months if you dont know what to do because of not getting any response and right procedures from Intec. I want a refund on my money, I will send their books back. They are quick to take money, but not quick to assist. As this is not my fault.
