They are absolutely useless in every aspects. I cancelled my contract on the phone but did not use PAC code because did not need too. They kept billing me and when I phoned they said by law if PAC Code not used then line remain active and monthly bill must be paid, ridiculous! Please don't use three mobile their personal don't let you talk all what they want is trying to make you renew your contract no matter how many times you tell them you want to leave! You phone one of their customer services and tell them what you want and when you phone again you need to start all over telling them what you said before. They are not reliable and should never be trusted.!.!.!
