No advertising but have to pay every month

Good day,

I have a business in High street Tygervally. With our Rental acc everymonth we have to pay for advertising. I have moved into the premisses in October 2017 Until today i have paid +- R 5200.00 for advertising and till today only one book came out in Nov/Dec last year with a pic of my shop with closed door and no contact nr. After numerious times asking when the adds will be publishe we dont get any answers. Then after asking agian my business was advertised on there facebook page. As far as i can recall Facebook is an free site and do not enquier any payment to even advertise. What legal way is there to get my money back ? I have done my own advertising with flyers and Facebook and through friends.

The office dealing with there advertiing is "The Blue Room" they dont even ans there phones!!!
