Just a follow up in case anyone else gets a letter from them. They are real. Delta uses them to send out unclaimed property or money. Apparently Endeavor owed me money and Delta used them to track me down. Don't know why they just didn't get the info from Delta since they know I am here. Anyway if you use them to get your money they take a 20% cut of the funds that are being sent. I got a call back from the company and they are cutting me the check now. So all the letter was good for is telling me that Endeavor owed me money. If you go straight to the company and not use Ryan you get 100% back.
