Olx India — fraud buyer made me approve rs. 3000 transfer through google pay

I had an ad selling some household items. My complaint is regarding a olx payment that i was accepting using google pay for the first time. Some person contacted me to buy my product and asked me to use google pay as it is easy to use. I downloaded and opened up an account and was following his instructions trying to receive money from him. But i didnt realise that actually he was requesting me for an amount and i accidently made a payment of rs. 3000. After this he requested for more money when i realised something is wrong and asked what actually he is trying to do. And he disconnected the call. The number he called from is [protected] and [protected] and google pay name used is shakeel and account id is [protected]@myicici. Please help me as i am a retired person and don't know how to deal with this fraud. I have attached that persons whats app picture and google pay id.
