A library claiming to be a college

Oxbridge Academy calls themselves a College but in reality they are just a library. I have paid for my course in full and finished my course and I have no certificate for it. Oxbridge has done nothing to help me I have emailed them on many occasions but nothing gets resolved. The only thing that this college have done for me is to send my my books. This college just take your money and don't take any responsibility for the services they must deliver.
