How do I tell O2 not to renew my contact

[dexdog]

My Pay Monthly contract is due to end on 30th June - I dont wish to continue with the contract so I want to tell them this so they dont take any further payments - however I cannot find anyway to do this - the contact us information  just keeps taking me around the same route and the quide to cancelling gives no information as to how I actually contact O2 to give them my 30 days notice - please can someone help

@dexdog You don't need to give 30 days notice: https://community.o2.co.uk/t5/How-to-Guides/Cancelling-your-contract-An-updated-guide/ba-p/1234852

thank you so i need a STAC code - one thing that isnt very clear - I am switching to another network and my new phone and number will arrive in a few days - how long will my O2 phone stay active after I have requested by STAC code - wouldnt want to be without a phone.

If you want to keep your number you need a pac code. 

If you dont, you need a stac code. 

Once you give either code to your new network it takes 2 working days to switch and cancel your O2 contract.
