Someone asked for advice on this forum over a journey they undertook that involved a change of train on Advance tickets. They were delayed on the first train. The guard issued a UPFN for the second train. East Coast cancelled the UPFN. This took more than 10 days to sort out.
Also there was the Darlington/Durham incident with the Professor, again East Coast cancelled the UPFN, although that took very little time (due to the involvement of the media; some of the InterCity TOCs don't like bad press because their passengers are more likely to be leisure customers who can pick & choose, rather than commuters who have to lump it)
I would go beyond the advice given by EC to appeal just to that awful debt collection agency and, in addition to appealing to them, appeal to EC too. But I would also advise anyone in this situation to seek advice from us, and to ensure that you know your rights.
In the first case I mention above, it took someone to speak to a manager and go through the rules in detail to get the UPFN quashed. The people in the call centre couldn't cope with it. It also resulted in a memo to staff instructing them to honour journeys where a passenger suffers a delay on any train company. (The "it's a different company" excuse isn't accurate, the guard made this claim but I've since seen the manual which says "a train company" not "our train company"!)
Also, just remembered there was also the Berwick to London trip whe a family bought separate tickets to York to visit the NRM, and started 'short' at York. Again, the UPFN was cancelled...
If they're on dodgy ground and you know your rights and you present a good case, EC will cancel it.

Just to put this into perspective, has anybody here been issued a UPFN for a route they considered OK, but the guard did not?
The brother of a member here used the infamous Carlisle-Newcastle ticket via Leeds, and was charged for a new ticket. However I do not know if he paid up or was issued a UPFN. However he did get his money back. I got the impression he coughed up and was given vouchers back but I could be wrong (I could look into it, but it's academic).
Of course that alerted Northern to the anomaly, and it was removed not long after (but only in
one direction initially)
Other people had been successfully using that route, armed with the relevant documentation from the Routeing Guide, for a while before that.
