My maid today received a call from the number +917282840902. As she cannot speak Hindi so well, she asked me to speak to this guy. He claimed that he was calling from RBI counter of Canara Bank on M.G. Road, Bangalore and that the debit card was blocked as Aadhar card is not linked. He had details on which ATM card my maid possesses and was asking for the details. Fortunately for us, my maid didn't have the card and I conveyed the same to him.
I have warned my maid as well to not give away any information and believe that we are safe for now.
Please, investigate and catch these scammers.
