PAC: blink and you miss it

You find a better mobile deal with another provider but how can you keep your number? Answer - request a Porting Authorisation Code (PAC) from your current provider - should be simple enough, except that it isn't The current provider doesn't want to lose your custom, so they make it really hard. First thing, build in a bit of a delay - it can take 24 hours for them to notify you of the PAC and then you have to give it to the new kids on the block within 30 days, otherwise it expires and the whole giddy performance starts again. A second complication is that the current provider might suddenly decide to make things difficult: a PAC can only be given over the phone, not by email or text. Why the hell not - they're supposed to be in the communication game, except no-one seems to have told the PAC creation fairies. Or rather they have, along with the instruction to make it all as ball-achingly difficult as possible. After 4 days of waiting for 3 to get their PAC ducks in row, patience has now worn so thin that a call to Ofcom is seriously on the cards. That is unless they really do phone back within the next hour, which I certainly don't believe or an instant is about to happen.
