Oplore.com - Package returned, refund not given

Ordered a phone case from Oplore.com. The case was not satisfactory, so I put a request for return within * hour of receipt of the package. The package was picked up within * days, on August **. After waiting a few days, I complained on their Facebook page. They deleted my posts from their Facebook page and have banned me from posting there. It has been more than fortnight and after more than ** email exchanges, they have still not refunded the amount.
