[Resolved]  ICICI Bank — My personal account linked to someone else credit card

I have a savings account with ICICI bank. But someone else's credit card is linked to my account. I keep getting transaction alerts for credit card on my ph. No. & My email id even though I don't have any credit card. I've tried contacting icici customer care a lot of times but they continuously fail to resolve my issue. Each time i call, they keep transferring calls to other departments & ultimately put me in hard hold & disconnect the call.
This is a serious security issue with my bank account.
Solve it ASAP
