I bet Wells gets away with it. Once the bureaucracy kicks in, you'll never even FIND the person who can sign off on returning the money. This is intentional. http://www.magicvalley.com/news/article_bd4270e1-e583-5835-9fb5-7bf2372ec8e8.html
There was a site called wellsfargosucks.org way back in the day. They had so many horror stories of disappearing money. People deposited and if they didn't keep their receipts, forget it... and sometimes with a receipt it still took many months...
stuff like that always needs an attorney. Settlement I'm sure will follow. Same deal with anyone who bought old "stock certificates." Since those companies probably got bought along the way and things changed...good luck redeeming those regardless of "value" now too!
