Apartment Savvy Chicago

They showed me few apartments and we finalized with one. 2 days later we signed the application with apartment savvy and paid 1st month rent and a $$ for application fee. Since I had signed the application form, I started selling my things in home and arranged for movers too.
I did not got any call from them for few days and when I called them they said they were not able to contact the land lord (?!). Later they called me again and said the owner got changed and the new owner is asking for $$ more for rent and $$$ as moving fee which was not told before. At this time I had already informed my current land lord that I will move out and I had rejected all other good apartments which came after I sighned here. I did not got any proper response from these guys and all I was able to do was to get my money back from apartment savvy and start seach for home from the scratch again. These guys are totally useless. Beware, you will loose your money and time!!
