I sent back a defective camera that I bought on Rakuten, but the shipment has been stuck for two months. I haven’t received any updates or messages, and the seller is no longer responding. What can I do?

hey I received a reply that my parcel of clothings are stuck at China for a month already! Arrived at China on 3rd June, why can’t it be smoothly delivered to receiver as its a month already? I have contacted the seller and plainly kept replying me at transit despite my update and instruction that the company/seller is to contact China Post as its stuck for a month already! I paid a hefty SGD30 to return rejected merchandise at my own cost for a refund..and I waited altogether 1/2 a yr in the whole process for the several deliveries between China and Singapore! Please do something, this is exasperating!

Sending dresses back cost £15 to send them back from post office did not no of any cheaper way as the was no return form inside refund please and no more information sent back on 3 10 2017
