Stalkbuylove — refund not completed

Hi,
I placed an order on stalk buy love on 19 june 2019 and it got delivered on 24 june 2019. After trying out the dress, i realised its not of the perfect fit for me. Therfore i tried placing a return request, but to my surprise, their order tracking section doesn't show my order as delivered. And because of this i am unable to place any return request. After 3/4 days the status got changed and i requested for a refund as the size was not available. However nodoby came to pick the parcel. Also, i tried mailing them countless times only to receive an automated response saying that the customer care team is looking into the matter. If the dress doesn't get replaced or returned, its of no use to me.
