Wynberg home affairs never answers their phone

I have been following up on my new passport every few days on the national helpline and it has been in quality control for over a week.When I asked if there was any way I could speed up the process as I am travelling overseas in a few weeks I was advised to go to or phone Wynberg and ask them to contact the processing dept in order to speed up the process but I have been phoning them for 2 days with no reply. The phone just rings and rings and rings
