cathfromsaron , you seem to make a point of posting incorrect information !
The sender and the sender ONLY can make a claim ! The sender needs to get a claim form from the post office and fill it in. Yes, the lost mail dept is in Belfast but they will not communicate with anyone but the sender and only then not until a fully completed claim form has been sent. No point at all in the reciever trying to contact the lost mail centre , they won't even speak to them.
