[Resolved]  HDFC Bank — complaining about verification process..

Address: Jharsuguda, Odisha

I've applied to open bank account in hdfc... Verification process completed.. I got mail from hdfc that my account was opened.. I didn't get kit.. Some one called me they said they are calling from hdfc and asked my date of birth and address.. I opened my ac in odisha.. But i got call from tamilnadu.. From this number [protected]..in the mail they said my password is my dob.. To open bank ac details..in the phone cal they only asked my dob. I thought it was verification but actually my verification process was completed.. How do i know is it fake call or hdfc bank call??
In true caller some people reported the no. Was spam? But i said details that i thought the bank kit was not arrived may be it was the verification process.
