I bought some stock in a small company about 30 years ago. I still have the stock certificates. The company is still in business. They were listed at one time on NASDAQ but were delisted years ago. It appears to be an OTC.
I'm trying to find out if my stock has any value or if I can sell it. Numerous calls to the company go unanswered. I sent them two registered letters which I have the return receipts but they did not reply to my letters.
My stock brokers don't have any suggestions on what to do. Is there any legal action or government agency I can use to find out what is going on?
