The worst mail company, ever!
They are the official service to receive foreign merchandise, so you have to get through them to pay any tax and fees (which are enormous amounts in Portugal).
On ordinary mail deliveries they constantly lie about having tried to reach a person, they don't even bother ringing the bell, they just leave the notice.
They usually make mistakes and send the letters to neighbours.
And the worst is that they even make ilegal procedures like giving registered mail to other people instead of the official recipient.
If you can, just avoid their services altogether!
