Worst College Ever = ******** actually

The worst college ever, I registered 2 years back for HR Management course. paid my registration and few monthly fees. but the service was terrible did not receive my assignments marks nor did I receive my internal exam marks. I sent them numerous calls and phone calls but no one wanted to help so I left them. Now they busy sending me emails that I owe them, I owe them for what. On the actual fact they owe me my registration and fees but decided to leave it because trying to speak to the guys is a waste of time. Their service is pathetic.what a joke
