Unlock Device Issues

[Jm1883]

Hello, I’m trying to unlock my device for use on another network. When I first tried I got an error message say they couldn’t unlock it as it hadn’t been used on o2. When I try and resubmit the request it doesn’t work as it says I’ve already completed an unlock request for this device. With seemingly no customer service, I’m a little stuck! Thanks

You'll need to call customer service.
Numbers here Guide: Coronavirus Community Help and Support 
When it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say "Upgrade", "Lost/Stolen" or "Fraud" if you have to, to get put through to someone.
8.00am is the best time to call if you can.
