IDFC Bank — Never applied for credit card - keep getting calls for verification, IDFC continues to ignore

I never aplied for IDFC credit card. I got several calls saying my application was approved. I asked IDFC to show me evidence of said application and no one was able to produce it for me. After several calls, one "supervisor" said she would investigate and call me back, She never did. i Still keep getting calls about my "application being on hold as it is pending verification". I need a resolution as no one seems to be talking clearly to me.

IDFC agents are great and hanging up the call, mid conversation.
