Ebay.in — Product purchased not delivered and unilaterally closed my complaint without looking into proofs which clearly shows nexus between courier and seller

Address:	400063

I Gaurav Aggarwal purchased 360 Rotating Leather Stand Case cover For Apple iPad Air 2(iPad6) from ebay site Artilcle no.[protected] on 22Nov2015 which was supposed to be delivered before 29Nov2015, Anandi Enterprise is a seller of this product. Paisa Pay ID that claims to secure your transaction is : [protected].
Initially after my many reminders they responded with one that it has been delivered to me & hence it has been closed. Then I showed them the courier details
with AWB no. EM[protected]IN from India Post from Kandivalli(Mumbai) to Ghaziabad (UP), that shows it was taken back to seller Kandivalli East from where it started.
Now despite of many attempts "ebay" is not responding & my money is not being refunded till now.
These multinational companies where claims to establish great standard in their home countries starts corrupt & malpractices when it does businesses in India. Because of their lax attitude & lacks of stricter norms they expolits customers & claims to be best.
Please help me to get this.
