Where exactly are you touching in or out during all this? It sounds
like you're being issued the £3 unresolved journey penalty fare for
not touching in.

I'm touching in at Gunnersbury, taking the London Overground to
Willesden (on my Oyster Z2-3 weekly travelcard) and from there to
Watford Jn where I touch out.
