Nope. Did my GCSEs a LONG time ago. In fact I was in the school year to actually do them.
Im not trying to be sanctimonious, and i'm not sure you're trying to audition for a remake of One Foot in the Grave.
Just having worked in the industry for many years it gets my back right up when after, what is quite a short period, in reality, its immediately a major issue.
I have know faults that have gone one for far longer than 2 to 3 weeks, and have actually stretched into months. I hope yours doesn't take this long, and it likely wont.
But taking to a forum like this isnt going to make any difference at all, your best course is to keep on at PN and they will keep on at OR.
(I used to work there too, so I know keeping on at the faults team does work.

)
YOu do have a thread about this on their forums I take it?
