ICICI Bank — Never taken any loan from ICICI still getting calls for payment

My friends & relatives, office and finally myself received calls for repayment of ICICI personal loan from following numbers : [protected] and [protected] between 15:00IST to 17:00IST 8th May. The caller claims he is from ICICI and as per ICICI records Kaushik Chakraborty have taken a personal loan from ICICI-Delhi branch in 2006. Kaushik Chakraborty is now a defaulter for the loan and needs to pay back the amount. That Kaushik Chakraborty was in HCL-Noida and a resident of Rajinder Nagar, New Delhi then. Myself also a Kaushik Chakraborty was also from HCL (but different year, diferent city), have no relation with any branch of ICICI-bank in any perspective nor with HCL-Noida neither with Delhi/New Delhi. I have never taken any type of loan from any branch of ICICI all over India. First of all I am not sure whether this is a fraud call or call from genuine ICICI's out-sourced callers. If this is a genuine call then I would like to notify concerned persons again that, I have never taken any type of loan from any ICICI or its related organistaions. Request concerned person to do a proper verification of their database. Hope I don't have to take help of legal advisors for unnecessary calls and harassments. Regards Kaushik Chakraborty [protected]
