They only care about money

So in 2015 I registered with College SA to study office administration and I was assured by Rentia that if after a month I want to cancel my course I can so before the month ended I wanted to cancel and I couldn't get hold of Rentia anymore she never returned my emails I then told them I want to take a break from my course cause I had some family issues which means I shouldn't pay for about 3 months I spoke to a Malcolm who then sent me the forms I filled them sent them back immediately but then Malcolm went awol my account was debited month end and when I contacted the school Malcolm was rude to me telling me that they school doesn't do a study break anymore as to why he didn't tell me this from the beginning I have no idea anyway I then told them I want to cancel my course no one was ever available to help anymore college sa kept on calling me for payment not giving a damn if I am still studying or not I made it a point to contact them once a week but never got any help I spoke to a lot of different people at college sa all promising to help but nothing happened now I get numerous calls and sms's telling me I need to pay and I get an email daily them promising to hand me over, I don't get why no one could help me it was a simple request and they treated me like **** and now they telling me I'm liable to pay the outstanding amount cause that's all they after money and they don't give a damn about me or whether I wanted to change the course or not, I'm honestly hurt by them cause no one gave themself the time to check on the one student that needed help. I'm really disappointed in your service if you guys can't treat customers right then what's the point of being in a business that assists customers
