Site/Plot of land

I bought a site from them in 2014,immediately in the process of trying to develop on it, I was told they made a mistake of selling a site/plot that belonged to works,and we where stopped.. Ever since, I have been tossed around pillar to post as a headless chicken, and a stupid human being.. Just last week after many attempts of trying to get the manucipality to approve my house plan, to try and identify the site for me and many several attempts to no avail.. I was told that my site the one I purchased and waited for all these years, have been sold to another person... My question is how, and I am not going to put myself in a badging position and pull back.. because I have waited for that plot of land, and wasted so much money in the waiting.. How can our officials be so inconsiderate. These people do not care about the dignity of the ordinary citizens they serve..
