E-Career App Inventor Course from Groupon

I bought the App Inventor course in April 2015, downloaded all the software form the MIT site as per the instructions. I became clear very early on that the course was for a previous version, version 1 which was no longer available or supported. On further research it was clear that this had been the case SINCE DEC 2014. In other words I had been sold a course that was defunct and for software that was no longer available. I tried to battle through the course but it was impossible, the versions are radically different. Quite frankly I feel that this is misrepresentation to the point of being **********. Groupon are passing the buck, and anyway don't respond to complaints on here but at least the news can get out, and others that were ****med can join in the demand for a refund.
