I've been trying since last Tuesday - text 65075, use app, phone customer complaints, speak to agent in live chat. None work. Keep getting 'we've encountered an issue with your PAC request...'. they can't tell me what the issue is. So I've decided to cancel the contract and go to O2 without the code. It's annoying because I now have to reset the phone number in every account that uses it for ID.
Very poor customer service
