Good news for everybody on 12 months contract with three.
I recieved a letter today saying that they are changing my billing to 59 sec for 1st minute call from previous per second billing.
So, I just got my PAC code free of charge and cancelled my contract.
This only currently affects Video Talk and Text 700, Mix and Match plans and Pay As You Go Flat12.
Best way is to ring them and confirm about any changes to your per second billing and act accordingly.
Remember you only have 15-30 days from now to cancel ur contract
