I would put zero stars but this tool doesn't allow me! I send some important documents to Portugal using the Royal Mail tracked and signed for service. This is advertised as 3-5 working days. After taking a week to even leave the UK (according to their tracking) the letters were passed to their shipping agent in Portugal -GLS. As far as I can tell they didn't even try to deliver it and just dropped it at a 'parcel shop'. No details of where this parcel shop was to allow collection or redelivery to be arranged. Royal Mail helpline were less than helpful telling me to call GLS in Portugal myself (I don't speak Portuguese) and, when in desperation at asked for at least a telephone number I was told to google for it. I eventually got through to a complaints dept who did at least supply a number for head of office of GLS in Portugal and my Portuguese solicitor then had to call the number, track down the parcel and go out to collect it. Goodness only knows how much this will cost me! I don't know about other countries but DO NOT USE this service for Portugal.
