Retour sur AliExpress

Bonjour,

J'ai commandé un téléphone sur AliExpress, mais je souhaite le retourner. Le vendeur m'a donné des indications, mais j'ai du mal a comprendre comment faire. Je vous copie mot pour mot le message du vendeur. (Je masque l'adresse).

"Dear friend

2,Pls ensure that the phone has our company’s sticker(the sticker looks like the picture,sticker on the back of the phone,pls kindly NOTE that if the return phone has not the sticker, we shall not assume responsibility )

3,Pls return the phone and all the accessories, put a LABEL inside your return package to inform me what is the exact problems of your phone and your ORDER NUMBER in aliexpress. after you send it back.inform me the track number also .then i can track its shipping details
Then i can know it clearly after i get it
