They are both a CA and a debt buyer. Definitely validate with these guys. A while ago as I was climbing out of my payday loan mess, they contacted my regarding a charged off payday loan that they had purchased. I sent them a validation letter that specifically requested proof of ability to collect (legal ownership or assignment) and I also have them two specific ways to contact me (email and to me in care of my attorney. Guess what they never responded.
On a good note though, they appear to be fairly on the up and up, the one phone call I had (where I stated that once I received their letter I would respond with a request for validation) was polite, and they even gave the mini miranda. Also too, they were even licensed properly in my state.
