Cheers, the pass is poxy beyond belief, surprised they've not switched to a sticker or something that ties it to the vehicle if they're turning into a money grabbing corporation.
I'll chase them up. The payment's not been taken so looks like the letter got lost along the way (think I forgot to send it, ended up taking it on holiday and posting it in Devon, so it's maybe awaiting the regular quarterly sorting in some backwater village depot).
