Change my myO2 email but O2 messages still being sent to old email address

[SMH1]

I have recently changed ISPs and previously used my ISPs email service. After changing my ISP I went into myO2 and successfully changed my email, which is also used to login to the O2 systems. I did this a couple on over 3 months ago but all my email from O2 such as my monthly bill is still going to my old email. I have just signed my next 12 month contract and again the details have been sent to the old address.

How do I get O2 to send any emails to the correct address as phone contact is currently for emergency only and there seems no way to message or email O2?

Thanks,

Stephen

This is an emergency for you, so give O2 a call.
