keeps calling

Keeps calling my wife at work. Even call her boss harassing her and was told Not to call back. But Ronald Lee(Fake name) kept calling saying he wanted to serve papers for the debt.

Ronald Lee was very honest and up front with me, very professional. I knew my loan was out there but had no idea who to contact and how to pay it back. Ronald contacted me provided me the number to the lender. I wast told by the lender the account was now in the office Ronald works in. Ronald offered me a settlement
and was very professional...why would he be legit with me and try to scam you?

YOU MUST BE RONALD SAYING THAT IS WAS HONEST... WHATEVER ALSO I HAVE THE COMPANY YOU WORK SO (YOU SAY) STP GROUP PHONE NUMBER I AM SHARING IT WITH EVERYONE 888-959-3804

Has called my cell several times, always uses a different name (this time it's John Miller, last time it was David-something) and claims his client filed a default statement against me.  Previous calls have included accusations of tax fraud, check fraud and threats of arrest.  The information he provides in these messages don't ever match any account number I have now or have ever had.  I don't owe anybody money and I pay my taxes every year (and they're always way higher than I expect!).  Based on what I'm reading about this phone number and the ever changing names/messages/id numbers, I think it's safe to say it's a complete scam.  Don't answer and don't call back.
