Received a pretty standard reply to my complaint !!!
Dear Mr Ebbs
Thank you for contacting us about International items that were posted on the 11th and 12th December, and the concern this has caused.
Please be aware that we aim to deliver International Standard items going to Europe within 3-5 working days and within 5-7 working days for the rest of the world. These delivery aims also apply to items being sent via our International Tracked & Signed, International Tracked and International Signed services. Delivery targets are not guaranteed though, which means we are unable to accept claims for delayed international mail.
We have a Universal Agreement with all postal operators around the world which means that all items sent overseas are handed to the postal administration of the destination country. Therefore, we don’t offer any guaranteed international services as we don’t handle the item outside of the UK.
Additionally, due to the millions of pieces of mail that pass through our extensive postal pipeline each day, we’re unable to trace individual items unless a specific trackable service has been used.
I hope you find this information useful and if we can help again, please do not hesitate to contact us, and please accept my apologies for the inconvenience caused.
