Wells Fargo Bank Account Or Service Complaint

Wells Fargo Bank account or service department,

(CD) Certificate of deposit Deposits and withdrawals Minnesota

I purchased - Savings Certificates from - in - of 1992, - each under each of my daughter 's -. Since 1992 Wells Fargo Bank purchased -. I recently found the original certificates and went to Wells Fargo ( -, MN Branch ) to cash them. They did a 10 day search and said they had no record of them and said they probably turned them over after 7 years to the State ofMinnesota Unclaimed Property Division. I called the Unclaimed Property folks, and they have no record of any monies coming from - or Wells Fargo Bank. Wells Fargo Bank said there is nothing we can do. We will not honor the certificates. I asked if the funds could be withdrawn without turning in the original certificates, and they said no! Since I have the original certificates and they have NO record of ever paying out the monies or even sending them to the Unclaimed Property Division of the State of Minnesota, how do I cash in these certificates and receive MY money back plus interest that was listed on the certificates?
