Kotak Mahindra Bank — Regarding credit, card due which i have not taken/scene

Address:	Bangalore, Karnataka
Website:	www.kotak.com

Dear sir,
Myself from dr. K. Sundiresan, i am a veterinarian by profession. I was working in bangalore, so my salary a/c was in kotak mahindra bank. My a/c no. [protected] somehow they registered my name for credit card, but i left the job & the city before i got any card, i didn’t receive any credit card. But for past 6 months they keep on calling me & saying there is a balance in my credit card & if i don’t pay they will issue civil charges.
I have not received the card, not used the card in single time, and not seen the card. But now they are torturing me through mails, calls. I called customer care no[protected]. But no response. I even tried to address them through online email form, but that’s not working too.
Kindly do the needful.
