Unable to set call-forwarding.

[Arch_Stanton]

I have a pay-monthly O2 account with a Nokia 6021 phone which is easy to use. Need to set up call-divert on it to my landline (as a reasonable adjustment for disabilities) but it keeps coming up with the message "Request not completed". Why will O2 not let me set up this divert?
