cancel o2 contract when phone lost for almost 2 months

[ashley_hmd]

I need to cancel o2 contract as I am paying for phone that got lost on a trip out, the phone is in my brothers name and the device plan has been payed off, the direct debit has been canceled too but I still pay for bill manually as I realised it doesn't cancel contract and I just need to know exactly what to do and what information I'll need to just cancel the contract which is just for airtime only now. I am not interested in trying to find the phone as I have new one I just need to cancel contract as soon and as easily as possible

How to cancel here Guide: Cancelling Your Contract 

or 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.

Your brother will need to call and give notice to cancel the contract.

He can contact customer services on 202 or 0344 809 0202

[ashley_hmd]

do you know what information he will need to provide for example security question or account number? or can he just give notice and then after 30 days it will be canceled?

They will ask for the mobile number and details from the account as well as some security details.

@ashley_hmd Why didn't someone just call O2 and report the phone as lost? O2 would have sent out a new sim associated with that contract's airtime which could have been used in any phone.
