Laptops

I bought i laptop from them and received a cellphone back cover , by instructions from them they told me to return to items and must use local post office to return the item ,they will refund the money for cost of items returned . After struggling the whole time with there support ,they finally decided not to refund me as promised . Alliexpress is a big ****. This is not my first time receiving something i didn't order . Big big ****. Never ever will i buy from them again
