PayU is a payment aggregator who helps merchants and customers to do online transactions. It is a merchant who delivers the services and gives refund/replacement as per their policy in case of any issues. Since the said transactions are successfully processed, any refund/resolution will be provided by the merchant only. In case you do not receive support from the merchant, you may raise a chargeback at your issuing bank.
