Union Bank Of India — Tejpal Scheme Branch poor customer centricity

Union Bank Tejpal Scheme Branch Mumbai 400057 Vile Parle East
Their contact number is [protected] and their email id is [protected]@unionbankofindia.bank

However they keep the phone off, or if the phone rings no one picks up.
Also they never respond to emails
I am in pune and having hard time communicating with this branch.
I wrote to gro.[protected]@unionbankofindia.bank head office but that was also not responded.
I also raised a complaint how to contact the branch that was closed without any resolution.
