still being charged for old contract

A contract doesn’t just ‘finish’. You need to give notice to cancel as per the term and conditions.

17.1 If you want to end your agreement, you must contact us through the 'Contact Us' section in our website at www.idmobile.co.uk/contactus and give us at least 30 days notice or alternatively you may log in to your account using the iD app and set a future disconnection request by selecting a date which is at least 30 days in to the future. If you prefer to contact iD Mobile via letter, please send this to iD Mobile, PO Box 686, Salford M5 0PA. You must include your full name, your billing address with post code, your iD mobile telephone number and the name of the bank your direct debit is with to help us locate your account. If you would like to give us notice beyond 30 days in to the future, you can contact us at www.idmobile.co.uk/contactus for more details. Whenever you have a No Fee Right to Exit you must exercise it within 30 days of it arising; if you do not notify us within this period, you will lose the right to terminate.

Hi ​@michael harrigan 

As ​@WelshPaul  has advised, you would need to contact us to cancel a plan, we wouldn’t just cancel a plan without a customers request to do so. This would just carry on.

Would you like us to pop you a message to help sort this, or have you already arranged cancellation?

Thanks.
