How do i cancel my contract?

[Max1]

I've been in my o2 contract for 24 or 25 months now and i have a different sim with o2. I still have my other one running and i am continuingly being charge for it even though i thought it would just automatically end. How do i fully cancel it? I cancelled the direct debit with the bank although when the payment time date came it said i had to pay it otherwise i'd receive a late payment fee and now says my next payment is on the 9th of May. Starting think this is a joke as i was told it would just stop. Please help??

Help here on cancelling and yes, your contract will continue on a rolling monthly basis until you do cancel @Max1

It was a wise move to pay the bill. Just give 30 days notice by calling 202.

No mobile phone contract automatically ends, for obvious reasons..

Cancelling the direct debit was the worst thing you could have done.

Also i would pay the outstanding bills otherwise o2 will lodge a default against you with the credit reference agencies and if need be will pass it to a debt collection agency.
