Passport Office Visakhapatnam — using abusive language over phone by an employee in passport office

Address:

Regional Passport Office, Visakhapatnam, Andhra Pradesh

I made a call to RPO Visakhapatnam from UK to enquire regarding PCC application, but the person speaking to me over the other end did not clarify my query which is acceptable, however he spoke quite rude and started using abusive language without any provocation and denied to tell his name when asked for.

If the answer is not known to them, they could clearly state it. Else, if the question which is being asked is beyond their scope of services, it should be clearly mentioned, rather than mere shouting over phone.
