have you told aliexpress support about this?Haha, this scam from AliExpress has word wide effect against 17track.net that is used by scammer and who does noting to resolve the problem with the shipping comany being used by hackers .
I've now seen 1 star average reviews given to 17track here : https://www.facebook.com/17track/reviews (320 x 1 star review on facebook with 1 star average ... ) and here https://www.trustpilot.com/review/www.17track.net (890 x 1 star review on trustpilot)
Sellers from AliExpress use an exploit or hack of the shipping company www 17post56.com or www hjyt56.com and they did not sent any package and claim using the link from 17track.net that the package was delivered and picked up by the buyer in 17 days to EUROPE by sea ?! The package is on sea from China to EU just 2 days ? What a scam ! Package also arrived on each stop at exactly the same hour is also a big proof of this fraud. Be aware of this FRAUD !
