Fair point WalkingATM, you not these forums are like, it starts as helpful advise and before you know it there is a side debate going on (no offence intended, I enjoy a good debate as much as the next person).
Hope you get somewhere soon. To be honest these things can normaly be sorted out pretty quickly by speaking to the right people. If a claim is being investigated then a claims handler has taken that decesion, speak to them or there manager to get an update, it's the least the can do. If not a call to the Chief Exec office should sort things out.
I had a similar problem with NU a few weeks ago and got it sorted in 2 days.
Good luck
