Apparently, they asked via email. However, I blocked all emails from that company address because they fought my unemployment and appeared to be LinkedIn stalking me. They also may have sent a letter to my previous address; however, it never reached me. The first time I heard of the mistake was from the debt collector.
I have asked the debt collecting company to put me in touch with the fund manager and/or retirement representative.
So what I am hearing is that the plan manager should have reached out and there is a process. I have taxes to pay if they remain in my IRA.
