Union Bank Of India — not responding to the customer calls

Address:

500004

I've been calling the UBI Saifabad branch at their office number for two days but no one is picking up the call. Today Also I called 2-3 times luckily someone picked and I told what my grievance and then he said he'll transfer the call to someone else and hung up the call. I tried calling again but no one is picking up the call. What kind of the service are they providing to their customer? This is really a shame on their part of duty they are doing.

Please do the duty properly.
