Institute Of Banking Personnel Selection [Ibps] — bio metric mismatch

My name is chiranjeevi v v s recently allocated to a regional bank through reserve list after waiting for many months my bank called for document verification where i had bio metric issue after two months of document verification everyone in my batch received appointment letter excluding me when i asked my bank they said "we have forwarded ur profile for forensics lab only after the reports we will give ur job" after saying that i asked for how many days will it take for that process they kept quite. I am ready to provide any document to prove my identity and my question is how long will it take for this process and will i get my job.
