It's infoyellowpages. They impersonate the yellow pages and try to scam businesses out of several hundred dollars. They're banking that the invoice will fall through the cracks and someone will just pay it. Especially if they call continuously to "collect" the debt. They tried getting all tough on the phone with me, but I told them they were a scam and would be contacting the attorney general if they continued to call. Got another call immediately after from a customer response team letting me know that they wouldn't be calling again.
When I told them we already have a sales representative from AT&T/Yellow Pages and asked for her name and contact number so that I could cross reference she informed me that they are different than them and did not give me a name or number. They said that they have been providing us with this listing for the past twelve months at the $450 previously mentioned in other complaints. When I asked her to send me an invoice for that past service she asked for an email address. I told her that she can mail it to the address she has on file. She just said thank you and hung up. Definitely a scam feeling.
