Hey @Add_02924 , Welcome to the 3Community 🙂
I'd be happy to help you here, before your plan is changed and you are moved to a new contract you will be required to accept the terms and conditions of this plan and you wouldn't be able to switch to a new plan without these being accepted.
I'd be happy to check the account here for you to see if the order was placed or if the order is currently open and we can get this cancelled for you. Pop through to me here on PM along with your full name, mobile number, address and date of birth and I can check the account here for you.
