Vijaya Bank — Status of Safe Locker not being provided.

My Name is Ashok Talwar (Age 68Yrs) and Indu Talwar ( Age 65Yrs) are the resident of Thane - Maharastra since 1992.
In 1983 while we were staying in Vadodara we got married. After marrige[protected] we had taken a safe safe locker with Vijay Bank Alkapuri Vadodara.
Since I was working with a company, we got transfered. We had kept our valuable articles in the locker. We did operate the locker upto 1986-87.
We have misplaced our locker number as well as its key.
Recently after our retirement, we started looking for old documents. It is true that we have not operated our locker for more than 2 decades. About a couple of years back we approched the VIJAYA Bank ( now Bank Of Baroda). Initially we communicated with them thru emails and also visited the Branch and submitted our case. We made a request to let us have the status of our safe locker held with them. The manager and their staff are refusing to indulge on this by saying there is no such locker on our name.
this is totally absurd and lie. The Branch Manager as well as their staff are not co-operating despite our several request. We had gone to their RO and directed to lodge a complaint.
It is hard to swallow by us as we are the bonfide and genuine customer. We are prepared to give any kind of surety or gurantee and we reitaited that we had taken the locker.
It may be a case that due to non payment of its rental, the Bank had to open/break the safe locker in terms of the contract. However we are fail to understand as to why the Branch/Bank is not providing the details/status of our locker and belongings.
Despite our vigrous follow ups, the Branch officials are beating the bush around. May we once again request the Branch/the Bank to provide us details of our safe locker held with them. We are prepared to provide any kind of surety or gurantee duly supported with our Aadhar Cards/Pan Nos etc etc.
