Hello MagnumPI, you have said exactly what myself and I am guessing the majority of the readers on this site are actually thinking.
Every time there is a new letter it just prolongs the agony of a result and further cements the way that any Minister or Department would look at this matter.
It really has to stop and be handled by legal people, there is no way you can fight this fight yourself and win, at the moment there just waiting for you to commit suicide or give up and then the problem goes away. Use the money that has been pledged and allow the fight to be taken over for you by professionals who will just get the job done.
Sorry, rant over but it is just so frustrating to know that using the correct people this would have been over years ago
