I am utterly disappointed and frustrated with my recent experience with Royal Mail. I had entrusted them with a highly valuable delivery which required guaranteed delivery and a signature from myself. Not only was this protocol disregarded, but the package was stolen from the delivery person. I had expected the service, especially for such an important delivery, to be seamless and trustworthy. Instead, I found myself dealing with the stress and complications that arose from their negligence. What's even more frustrating is that I have provided proof of the stated delivery requirements and evidence supporting the incident.
