Hi JohnFoz,
Thanks for coming back to me via private message with your update. We only use private message if we are needing to request or send account sensitive information. Anything else can be posted in the Community instead.
I'm sorry to hear that the SIM has not been delivered yet. It can take between 3 - 5 working days. As it was sent Monday, you won't be out of that timescale until Monday 21st Feb. If you've still not received the SIM by then, please pop back and let us know via the Community and we can escalate things then.
If you would prefer to cancel then we're not able to do this via the Community so you would need to call and speak to the team on 789 / 0345 600 0789 for them to process your cancellation.
Keep us updated on how things go.
Thanks,
