Aliexpress.com - Package return shipment cost is higher than the product’s cost

On dated **-**-**** (Order ID: ***************), I have ordered two pairs of UnderArmour shoes out of which one pair was not available with the seller and was not shipped. The second pair I got was ***% duplicate and the sole was not pasted properly. I am pretty sure that the product is not genuine at all. I have asked to return another pair of shoes and it was told to me that seller will pay the courier/ shipment charges but at last, he had refused to pay the same and still I am waiting for your kind interference between me and seller.
As you know that the amount of shipment for an individual is quite high i.e. more than the cost of shoes that has to be returned but for AliExpress it is almost nominal. Kindly resolve the issue as the product is still kept in its original form.
