Mobikwik — Cibil impact without any prior intimation

Address:

H-29,Prem Nagar 1st

Got a call today and the representative said he is from Mobikwik his name was Rajesh (Sr Manager)
He was very rude over the call and sent me and otp and wanted me to share that otp with him . He said i have used the amt rs 500 for a mobile recharge however there is no transaction is my mobikwik history. I called him again and asked kindly inform the complete information regarding that recharge then he said i have used the amt from Zip and i have already checked my application where the available balance for Zip is Rs 500 which indicates i never used that feature . Mr Rajesh was threatening me that if I won't pay that amt then he can effect my cibil score badly and cut the call. I tried to call him again but the number is not reachable. I need to knw how the transaction went through if there is no payment history
I am attaching the screenshot of my wallet where you can se tha available balance in ZIP which i never used and 0 transaction history.kindly resolve this issue asap or i need to take some hard steps against mobikwik. Contact no. Of Rajesh (Sr manager) is [protected]. I don't have any issue to pay the amt but atleast i need to knw where and how the transaction went through. And who is responsible for this.
