AliExpress complaint: Products not delivered

I have had a number of products that have not been delivered to me and are being marked as delivered. Numerous times I have tried to get in touch with DHL who gave me an address that did not have the items or would just give me German operators who know no English and end up hanging up the call. Once I got in contact with Ali Express through the dispute function they would state my claim was invalid asking me to show a note saying the parcel is missing. This is already hard enough given the fact the communication is through the phone but even worse since most people seem to be incapable of speaking English in DHL. This should not even be happening, I should not have to be chasing for a parcel that I ordered because the shipping company never bothered to ship it and marked it complete. Ali Express are being very hard to deal with in the process.
