Carrier attempted to deliver but failed, and usually leaves a notice and will try to delivery again.
Possible reason: item refused by addressee; incorrect / illegible / incomplete address; expired retention period; addressee absence; etc.
If you have received your package, please ignore this notice. However, if you didn't, we advice you to contact the carrier to arrange a re-delivery or collect your item. Please note the carrier has a collection deadline, if you don't pickup your package in time, it might be returned to the sender.
