Respected Sir/ Madam,
I have received a Threatening call some times back from their number 022 678 50907 on my ICICI Bank Credit Card registered Mobile No: 9869 733614 and I had informed ICICI bank Customer Care vide their number 022 33 66 7777 . They informed that I donot have to worry, as no pending amount is shown in my account and my Credit Card is Clear
Yesterday, 18,03.2016 , I had to literally run all the way from Dombivili Station to my House, as my old Father called me that a Recovery Agent has entered our House and is demanding repayment of Pending Balance on my Credit Card , amounting to Rs. 85,000/-
The details were in the name of VENKAT Iyer and also matched our House address. However the Credit Card number differs. After complaing to ICICI Co6nsumer Care on their Number 022 33 66 7777 and Spoke to one of their Office Mr. Afzal ; Ref No: SR 405649571, I found that due to some error in Andheri Branch, there had been a Mismatch and I am harassed for no fault of mine.
Why should I not take them to court and seek Compensation for the Harassment? Kindly advice
