Axis Bank — fraud with me

Address:

242001

R/sir 1 june 2017 an incident with me i have one call from unknown person he was said i am taking from axis bank for increase amount in your credit card so pls tell your back side of credit card cvv no. He was calling again and again with message of axis bank coming on my mobile that time. He convinced me to give cvv no. After that from my credit card 8500rs temporary credited. I was call to customers care and told about incident they told me to do online fir, dipute form and send to axis bank with image of broken credit card to bank email id. I had done all formalities. They didn't tell me to submit any incident letter so i can't send it. So please consider my case and return my money. When i was talking to customer care in that time i asked him any fomality is wanted or not then he clearly say no you didn't had any formality. Before 4-5 days same amount is showing in my credit card statement then i was call to customer care about this problem then he say incident letter is not send from our side so that the amount will detect.in that time if anyone said about incident letter than i surely submit it. I trust very much on axis bank. My monthly transaction approx rs. 50000 per month. I am 6 year old admired customer of axis bank. So please reconsider my case and i hope you will understand my feeling and definitely you will help me. Thank you
