Hi @Richie14
Welcome to our Community Help Forum:)
Thank you for making this post regarding your new SIM, I'm sorry to hear that it was sent to your previous address and that you've had difficulty getting in touch with us on the phone. I can arrange for your address to be updated on our systems and for a new SIM to be sent. I shall send you a private message to obtain the detail required now. Please look out for the purple envelope in the top right corner and get back to me when you can.
Best wishes,
Serena
