Lazada doesn't care whether Items are delivered or not.
I bought a Aqara D00 digital door lock during 9.9 which cost me $725 with installation. The seller sent me a piece of black plastic with a label sticking on it stating my name and address and the name of the item. They just throw it outside my door. Then the seller said item delivered and payment was automatically released to them. I requested for a refund from Lazada stating the reason with a video and photo of the piece of plastic but was rejected. Seems like Lazada isn't interested in doing a honest business nowadays.
