Damelin not assisting even after they promised

I had some studies through Damelin Correspondence College which I had to cancel due to service received from the college.<br> <br> It was never cancelled on their system and now my credit score is messed up, after taking it up with them I received no assistance, I then posted my complaint on Hellopeter and received a call from Damelin advising they will sort out my issue, it is now almost a year later and the problem still exist.<br> <br> DON'T KNOW WHAT TO DO TO GET THIS PEOPLE TO DO THEIR WORK, NOBODY SHOULD EVER USE THIS STUPID COLLEGE!!!!
