Rang to book sticker installation today. Unfortunately I don't know my CCSN so it wasn't possible. I asked the bloke I spoke with to ask the girl who rang me last to ring back and he said he'd try but he's also going to email my CCSN.
Anywaysanall, I haven't got an email yet (c. 3 hours on) so if I don't get one or a call back I guess I'll just drop in on 22nd when I'll be there for the meter seal. The current stickers are good 'till the 23rd and, to be honest, nobody ever looks at them so if they can't do it when I'm there I'll probably manage without them till December. I should probably maintain a record of all the efforts I've made to get them just in case I end up before a judge, however unlikely that may be.
