Never sent me a letter. Just seized my account. Eventually got it sorted.
I love those phone calls. I especially love the one I received with the caller having a heavy Asian accent. “You do bad thing. You go jail. You send money, you no go.”
Glad you got it sorted. I don’t know about your situation, but my simpler one made me feel like I was dealing with a multi-handed creature...and none of the hands knew what the other hands were doing. I didn’t owe money but there was some kind of issue with several IRA rollovers. They kept sending me forms to fill out as if I were the organizations holding the IRAs. Never could get them to understand I was the customer/IRA owner. Even the financial institutions didn’t understand it. Eventually, they stopped mailing letters. (I responded too every letter they sent.)
Heck...my kids can sort it out when they inherit the IRAs.
