Worst Institute for customer service

On the 21 Oct 14 Paid for studies for CD. 18 Nov 14 received only email content. requested CD and hardly any response. 10 Feb 15 wrote exam. Never received what I was paid for. requested refund between email and CD content. promises of refund and results, never received any response after I was promise my scan results and after response of still in process by management and management has signed off the payment. it is now the 24/07/2015 have still not heard from the institution of what is happening with the matter. I can believe that in workshops they are reliable but studying through them is not recommended
