INTEC COLLEGE HAS MADE MY LIFE A LIVING HELL!!!

Intec college has made my life a living hell!!! I canceled my course with them in 2016, one day after my cooling off period, due to their incompetence. I had to pay the full course fees which I did. However they put a judgment on my credit score even though I paid in full and now I'm being denied a home loan. It's a year that I settled my account with them and it's still not removed from being in arrears. Everytime I call them they keep transferring me from department to department with no help.
