[Resolved]  Ebay India Pvt Ltd — Refund not received

I placed an order worth Rs. 20300in (www.ebay.in) via paisapay mode using my debitcard (IOB). The seller could'nt ship the item, so ebay refund the money on 6th of feb via NEFT. They provided RRn and Auth Id. to provide in the bank to trace the funds. I shown the RRn and Auth ID in Indian overseas bank. They said they doesn't know what is RRn. and Auth ID. The bank needs UTR no to trace the funds. I asked ebay to provide UTR no, they simply said we wont provide UTR no after refund happend. What can i do?
