My mother got the call from 8404976709,asking ATM card details,he said that ur ATM card get blocked.when I m asking him from which bank u called,he replied kotak then we reply,don't have any Kotak account then he said I am from Maharashtra bank,ur ATM got blocked, need details. When I said him we will go to near branch for enquiry,the caller used bad words for me. Beaver of such kind of call, should take some action for such fake call.
