Hello Sir,
As someone already explained, the money is with ebay and not the seller. Also note that we do not see any order confirmation for ebay id nidhipurnapatre. You would have got your refund by now. If there is no refund yet, please contact ebay customer support either by writing to incswebhelp@ebay.com or through live chat and phone by visiting the contact us page on the ebay website.
Thanks,
HYDSTORE
