[Resolved]  Olx — fraudulent transaction

I had posted an ad for sale of my bike on Olx India.
On 17 june, 2019.A person named kamlesh chaudhary called me for the bike.He was ok with the dealing and I trusted him and gave him my Google pay number.
Instead of transferring the amount this person took Rs 20000 from my account.
He took Rs 20000 by keep sending request on Google pay.
He said me that he transferred money on Google pay but he requested me to pay him.
Later came to know that he is trying to debit the amount from my bank account.

I want the refund of Rs 20000
Help me please to get my refund back.
Please identify such fraudulent person
I attached all the evidence about fraudulent transactions.
I am requesting you to take some action against him.
Kindly resolve my issue. Waiting for your positive response in this regard.
Otherwise he can do any fraud off all people.
