Sorry I should have elaborated more on my earlier post. The e-mail I sent to the Sun was a brief outline of the farce that is JPA and didn't contain any of my personal details.
The money I am missing is my four and a half year bonus that I was entitled to around two months ago. After tax, it works out at about £2400 or thereabout. I have spoken to my seniors who have in turn spoken to the station admin unit and JPA. All they get is the same answer that I get, someone will call you back in 10 days!
Sorry if I confused or misled anyone.
