We asked in Sibonga Municipal building about Fast track and they said it doesn't exist - all applications take the same time, however when we received the official certification we were asked why we didn't pay for fast track. So i would be wary about what you pay for.
End of the day, don't expect miracles. Things are slow here. My parents were with us when we visited the Municipal office after the wedding, my mother felt like she had gone back in time 50 years. All typewriters and filing cabinets...........
