Royal Mail

The Royal Mail Tracked & Signed service to Europe isn't fit for purpose. I run an internet business and post many items around the world, recently many items to Italy, Germany have no been delivered using the Tracked & Signed for service. This is due to the Royal Mail passing them onto GLS (a company they own), which has to be the most incompetent delivery company on Earth. We pay extra to send items through the Tracked and signed for service, yet GLS can't seem to deliver any of them. I will be using a different courier in the future as I can't afford to continur to use the Royal mail if they continue to use GLS.
