Refuses to assist with exam rescheduling

I signed up for a Cima course in 2013.<br> Due to family constraints I was unable to complete the course within 13 months.<br> Currently SA Colleges are refusing to assist me to re-schedule an exam unless I re-sign a contract with them to list me as a student - and pay them more money. They where not forthcoming with this costs when I initially signed up for the course and told me \you can take as long as you want"<br> I will really not recommend SA Colleges for any courses provided."""
