Got the same letter yesterday and called them. They said my Husband had talked to them on the phone in 2008, and agreed to the charges of $624.99. We asked them to FAX the contract info to us but they did not. My husband called back last night and they said the contact person ( Mr. Cutler ) does not work for them anymore, bull crap, the letter was printed on January 12, 2011. We have NEVER heard of yellow pages express. If we were so behind on payment WHY haven't we received a BILL before now ??
