Indian Overseas Bank — fraud call on update aadhar card

On 17th feb 2018 posing as iob employee from head office and asked to update aadhar card and then after collecting it he mentioned debit card also should be renewed and collected the same and he asked to share the otp for linking and using that otp he withdrew about 50k with multiple times saying share the otp so that amount will be credited back. Would like make every one aware of the scam and we will be submitting a complaint in the branch.
