Mobikwik — someone tried to fraud

Sir, i complained before regarding mobikwik wallet (Now no issue using my wallet) at this site, regarding this someone call me & say that i am from mobkwik customer service (His ph. No. [protected]) and said, open your mobikwik wallet & tell me pay and store 6 digit otp & ask about wallet balance and which card add wallet money, tell me cvv no. Printed back of card. I told them wallet balance & other information but i din't told about cvv no., when he asked about cvv no. Then i understoopd he is totaly fraud. After 30 minutes he booked xiaomi mobile from my wallet rs. 13999/- but failed to transaction amount. I atonce complained in police and cyber cell and given all the infomation to police. Is that possible any member of mobikwik service center ask about this type of information. Please take against those people who try to destroy the reputation of mobikwik company.
