So my husband and I received a couple of checks in the mail along with a W-9 to fill out and a letter of explanation. We knew nothing of Conterra energy or even that we had mineral rights in the area they specified in the letter. I have tried calling the phone number and also other phone numbers on the web and no one is answering the phone so I can ask questions. I’ve left messages and now it has been almost two months. I need to know if it is okay to cash these checks and if this is a legitimate thing before I go sending them a w-9 with all our information on it. I’m beginning to think it is all a scam to get our SSN because I can’t seem to talk to a human, only voice mail. Any advice?
