I posted a tracked package from Northern Ireland to the Inland Revenue. It was important. It didn’t arrive and tracking was non-existent. I inquired at the Post office from where I sent it. They had no information but handed me a form to try to reclaim the postage. No help. I prepared a new set of documents to send to IR. I posted them this time registered post via the Irish postal service AnPost. I was able to track it to Heathrow. This second package never went beyond Heathrow. It hasn’t arrived either. I ended up preparing a third package and send it with friends to U.K. who despatched it via courier. It arrived safely. Enough said.
