It has been 15 years since you deposited the certificate.

The bar by limitation might be staring at your claim. 

Do you have the acknowledgment of depositing the certificates?

Approach a very able counsel specializing in such/consumer/banking matters with all docs on record, for a considered opinion.

You have to send a legal notice to the company with full facts and obtain acknowledgement from them properly. You can file a money recovery suit in appropriate consumer forums. Do act imminent.
