Royal Publishing approached me by phone to advertise; have not shown proof of advertisement Peoria Illinois

On May 15th, 2015, I received a phone call from a person named Rachel with Royal Publishing.  She was trying to fill up a school program with last minute advertisers for the Oviedo High School Baseball Championship game. 

I told her I was interested.  She told me what the price would be for a quarter page ad - $155.00.  I said okay.

She sent me the bill to my workplace.  It was then that I realized I didn't speak to a student, as is typical, to sell the ads, but rather a publishing company.  I received one piece of paper with the amount due, and how to pay it.  On the back was a picture if you will, of my ad.... black and white.  No program, no proof that my ad ever went into any school program. 

I called the company to ask that a copy be sent to me before I pay the bill.  She said she could email it to me.  In my email, I received the same black and white picture of an ad.  I returned this email and requested that the program be sent to my business address.

I have not heard back yet from them.  I am very concerned that this is a rip off, that no ad was placed in a fictitious program.  I am also concerned that they will be harassing me at my business workplace. 

Thank you for your time.
