Re: Slamming protection first please
This is the main (only?) aspect that makes the current system worth retaining. Getting a PAC from the current network should reduce to almost nil the changes of slamming (a popular practice in the Energy industry or have regulator memories forgotten this?).
It should be possible to get the PAC via the current operator's website (I think the story notes this as an option). People calling their current operator should get through to the right person within 5 minutes. The PAC should be issued (verbally and by SMS) within 5 minutes of the call being picked up. Fine all violations of these times at £10k per occurrence. This keeps the slamming protection of the current system but ensures minds are focused to prevent existing operators taking the piss by making it obscenely difficult to get the PAC.
I've only moved operator once - from Orange to Vodafone in 2006. Orange claimed they couldn't give the PAC over the phone or by SMS and could only post it for security (total BS!). Voda held the agreed deal until I got the PAC then did the port. Since then I've called Voda several times for my PAC as a starting point for contract renewal and always been given it within 10 minutes of dialling the number (YMMV as always!).
