Jabong.com — refund of returned products not yet received

I have purchased two products from jabong.com with order no[protected] and109666672988924221801. I have returned both these products but i didn't recieve any refund for the same. I have also raised the issue with jabong and they provided me with the reference nos and instructed me to contact my bank and i did the same. My bank has fully investigated the matter but they could not find any trace of the transactions which is claimed by jabong. They further said that the reference no is for the sender and could not used at the receivng end. They also instructed me to ask jabong company to raise a complaint in the sender's bank.
I asked jabong company to check with their bank but they are refusing to do so.
Please help me.
