Cancelling my new sim only a/c

[Veronica59]

I have a sim only a/c which has not been used, the phone I bought is faulty, I cannot get to talk to anyone, have returned the SIM but still getting messages on the app re payment date, upgrades etc. I have written to O2 on the hope they will cancel, I do have another Sim only account.

You need to cancel correctly and pay off any remaining period of the contract, returning the sim card doesnt cancel it especially outside of 14days. 

How to cancel the contract is here Guide: Cancelling Your Contract
