Yellow Pages Oregon imposter

Victim Location 97217

Type of a scam Yellow Pages/Directories

Receptionist received fax from Yellow Pages Oregon, asking to confirm/correct the address and contact information and fax back the info. It said the form that "This is Not a Bill" . A month later we received an invoice for $2,376.00 . Now, they send us to collection, the collection name is Open Business Solution, LLC. Might be the same company. I refused to pay for this scam.
