Hello @melbarichards_1 ,
Welcome to the community,
You will have to ring customer service to get this cancelled, which you can do in the morning, but it is possibly already being processed, so if that is not an option, you can send it back or when DPD deliver it, you can refuse it and it will be sent back to EE.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
