How to contact O2 not via sms?

[JO666]

I’ve relocated from Uk back to Australia. Now using Australian sim. Trying to finalise O2 Uk account but cannot see anyway to contact via email. I cannot call due to international call charges, sms not an option as using Australian sim with new number. The previous email I had used has now been discontinued??
