Account closed, money gone

My account was closed while it had a positive balance. No call, no correspondence at all. Apparently the account was closed due to inactivity, but it had a positive balance.

I'm now attempting to have my money refunded and it has turned into a nightmare. The buck is being passed and nobody is able to give feedback.

I can't believe that a bank, which has sophisticated IT systems is unable to assist me. Apparently due to the account being too old, there is a delay in retrieving the information.

I would appreciate any assistance in this regards. Incident ********** 4
