This happened with my family.
We went to the bank where we hold our account. They spoke to the counterparty who initiated the transfer and decided the best course of action would be to send the money via NEFT after receiving their ID. Money was sent, they confirmed they received it and nothing happened after this.
I guess problems might arise if they send you a link to pay or claim later that they didnβt receive the funds and keep calling you.
I donβt think they can claim a chargeback once u send them the funds without your approval. But I can be wrong
