Terrible Service

I enrolled to study with Intec in October 2015. I have been offered a job overseas, so I needed to find out if I can write the exams in the UK after I have moved. 2 consultants ended a chat with me after I asked, one put me back to the recorded message, and one said they don't know, they'll try find out. 2 months later - still no response. So I decided to cancel the course. I sent the form on the 28th of January 2015. Still no answer. In my original email when I signed up I was told the course will cost R 15938 as I get discount from enrolling early. On my account I was billed R 19923 with no discount. SO now not only am I being given terrible service, I am being ********** and **** to. They are very eager to take your money and debit your account monthly, but they give terrible service, bill customers wrong and can't even find someone to answer a question.
