I ordered from Aliexpress and the vendor did not deliver the product. I contacted the seller (Global Drone Store) multiple times , fist they said the merchandise was returned back to them by their shipper and they will refund and it will take 9 days but even after 20 days still no refund. I opened dispute but it was automatically closed after certain days without any answer. There is no mechanism to contact AliExperess, there is no customer server number or email except online automated survey that is question and answer pre-populated information. Please do not risk you money and avoid it and better to use Amazon.
