About Nainital Bank
Two lines, split by what has gone wrong. Nainital Bank keeps 1800 180 4031 open 24x7 for ATM disputes and unauthorised or fraudulent transactions, while general queries, feedback and other grievances go to 8069840140 between 10 AM and 6 PM. That second line is shut on Sundays, bank holidays and the 2nd and 4th Saturdays, which is worth planning around.
The bank does not publish a general customer care email, so written complaints go through its own online complaint portal or your home branch. Head office sits at Seven Oaks Building in Mallital, Nainital.
A useful detail the bank states itself, service calls reach you from 1600308474 and promotional calls from 1409269311. Nainital Bank will not ask for your OTP, PIN or card details on any call, so put the phone down on anyone who does.
