Legal Question in Real Estate Law in Illinois

This is more a matter of sensible action than a legal matter. You either need to get them to get something done or consider cutting your losses. As it is, you have put three years, both payments and time, into something you thought you were going to own and, now, if you can't work out the details it is unlikely you will be able to pursue any legal action that would be worth the cost, risk and trouble. You could have been paying on something elsewhere and now three years later you may be at square one.
