The Wisconsin BBB is warning its accredited business members about a company called OYP (online yellow pages) Group, located in Plattsburgh, New York. The company has more than 500 complaints and an unsatisfactory rating with the Upstate New York BBB office.  According to a Wisconsin BBB accredited business, OYP Group mails to businesses what looks like a collections notice for an advertisement in an online yellow pages-type directory. The only problem is...the company didn't place an ad! If you have a problem with this company, be sure to file a complaint with the BBB.
