aliexpress — I'm complaining about shop 2986021 - an AliExpress website vendor

I'm contacting you as I ordered 2 items of Bicycle Headlights T6 Highlight USB Charging Riding Lighting Mountain Bike Lights Waterproof Glare Lights via AliExpress website and the seller mentioned. I paid for a faster delivery to receive them within 10 days and waited patiently only to receive an intact package with only one headlight sent by the seller as it wasn't on the way the second one got lost but not put in the package initially by the seller. I messaged the seller through AliExpress and was given numerous incompetent answers when asking them to resend second item with express delivery due to the inconvenience so I can receive them and use them. As time of the delivery and receiving items in good condition is CRUCIAL and my legal right as a customer! I was again answered inadequately and my time wasted for a month already when I could have received the items by now if they had resent it when I first kindly asked! I've lost my patience and required to speak with a manager so we can expedite the process and I can receive headlight with express delivery as nothing can compensate the time wasted and inconvenience but this is the least I can receive - something I paid for in advance and done my part of the contract for - expecting the same on their end!
