Change my account email address - Verification does not arrive.

I need to change my account email address.  The verification code never arrives.  Ever.  I have tried so many times and NOTHING.

And getting help from $FINITY?  Impossible.  Stupid AI support does not ever understand my question. 

Should I just give up on ever having communication of any sort?  never again a bill...oh, see, this could be good....
