HELP JB MARKS Traffic department

My son received a fine. I have been trying to sort this out for two months. Fine should have been paid on the 10th of Dec, the banking details on the fine is not right, can not EFT and bank can not help. Can't pay directly as we live far from Potch. Also after I tried numerous times to get a hold of someone telephonically, I finally got a hold of them today, they advised they are off line, there is no one that can help, they will be off line till January. I asked what will happen if we are unable to pay the answer my son will be arrested. WHAT SHOULD WE DO AS I DO NOT GET ANY HELP. I just want to pay the stupid fine.
