This is such a scam!!! they have been harassing the business I work for for three years.  Do Not give them any money.  They say they are calling for local school district.  I have checked with district and they have no knowledge of this company.

Do not...I repeat...DO NOT give this company money for an "ad".
It states clearly on the bottom of their generic invoices..."Company is not affiliated with any school".
.

They called me today saying that my business owes money for their "winter sports poster" I do not recall advertising with them. She had hip hop music blasting in the background, very unprofessional even for a scammer!!

Received a call from this company today;  cannot confirm any link to the school in which they say they represent.  

We were scammed by a company posing as a school advertising representative a few years ago and this appears to be the exact same thing.

I think it is a scam. Caller claims to be gathering advertising money for local schools. Contact the said school before you "donate".
