I have a credit card ending with 4311 with HDFC Bank. In 2012, I resigned form CTS and my registered e-mail id was CTS e-mail id , so I called customercare to change my e-mail id and they took my email-id but never changed it due to which I never got the statement. Now they are just adding the interest for the last 1.5 years on the credit card. Further after I decided to pay the amount in the last month, they started calling my friends and family and they started harassing me. They took the contacts from facebook which is completely illegal, to access someone else account. I agreed to pay the amount but now when they are harassing me I decided to lodge a complaint because it was their mistake not to send me the statement as I intimated them that I have resigned from the job and further inspite of their mistake they are harassing me. Please look into the matter.
