Dear Ms. Valentin,
Thank you for placing an order and we are happy to serve you. The tracking number that was sent to you was probably automatically generated by the system and sometimes when you are redirected to its website, you have to manually input the tracking number.
However, We can assure you that my website is legit and the tracking link that I sent you is real. You can try the same tracking link one more time : https://www.17track.net/?nums=4PX3000444697887CN or you can also try this usps link : https://tools.usps.com/go/TrackConfirmAction?tRef=fullpage&tLc=2&text28777=&tLabels=420770269361210914550009318661%2C&tABt=false
