Is Mesa Financial illegal/unlicensed?

they just called me. i keep my cool. they go crazy saying oh yeah were going to summons, your balance is 350 on a 200 loan you took out. i say give me some validation, ill pay if its legit. they say they will send via email. i say no, send it through the mail.

then this person comes back and is the sweetest thing ever, saying oh yea we'll settle with you for 262 now. i say send me dv, we run around circles again. i explain i'm only paying the principal if they cant provide proof, since illegals i wont pay the interest.

person goes away, says we can settle with you for your original loan amount of 200. she says we want to set something up over the phone today with credit card. i say im not paying anything until i get settlement letter specifically saying this debt is paid in full upon paying the 200. lady had to wait for upper, so i told her id call her back.

im 99 percent sure mesa is illegal/unlicensed. just want to make sure.

-i live in a state where payday loans are legal as long as they are licensed in any of the 50.
