Non existent customer service

Simple account upgrade and no one is able/willing to assist. Trying to have this done from abroad seems absolutely impossible. Have even sent FNB my foreign contact number (Australia +61) yet nothing but a lousy email saying my complaint has been received and to expect feedback within 24 hours. It has been two weeks! This after other requests have been made in the weeks prior to this. Not even sure why it gets treated as a complaint as it is technically just an account upgrade.

If you are unable to get hold of me via phone as I assume is the case (even though I have provided my foreign contact number on multiple occasions) the least you could do is communicate via email.
