It's a tricky situation.
The definitive answer would come from a quick phone call to OAA. However, assuming you paid upfront for the cost of your course then probably you have no option but to resolve the issue directly with your current FTO.
Try to get as many of your coursemates together, call a crisis meeting with the FTO management to get commitment in writing to your satisfaction and if that fails, you could investigate legal advice for a full refund enabling you to go elsewhere. If you paid your fees with a credit card then get the bank involved too.
