Kotak Mahindra Bank leaks Credit Card details of the customers
I had earlier got a call from a number Delhi number stating some rewards points had been lapse and we would issue a new card with 8000 reward points.They were smart enough to have all the details of mine and than step by step they confirmed every single detail.As a aware customer we should never disclose or share our pin & opt number to anyone so i followed it.Immediately i called the customer care number a got my card blocked.
Received a new card just one day back and in the morning just next day a got a call from Delhi number [protected] stating you have changed your card and we have promotional scheme please verify your details with all cvv & otp details.They just told me you will just receiver a pin on ur mobile just confirm that.
The point is how did the new card details got leaked to the fraudsters in just one day for the new card number.All things are only pointing towards the that kotak mahindra bank leaks the information of the customers and make money.
Never ever do banking with kotak mahindra bank they misuse your details and earn commission via giving details to fraudsters.
