<prompt> Human: - Company I worked for was acquired- My old 401k was to be rolled into a new one with the new company- The bank handling my old 401k mailed me a check for the full balance of my old account for me to apply to the new account Straightforward so far...- Between the time they mailed me the check 6 weeks ago and now, I would have seen about an 11,000 return on my investment. - BUT...they mailed the check to the wrong person, so I never got it. And I didnt realize what was going on until now. I didnt even know a check was coming. I thought the would be transferred automatically. So they made a mistake that cost me a significant amount of real money. They admitted their mistake but they are not going to make me whole. I am no longer their customer and have no leverage in the situation. So I am out 11 grand. Do I have any options here?  <response>: You could have lost money if the market was different. In that case should you be paying them?
