Sanral administration sucks even when you are paying

First of all, I wish there is an option to give zero or minus stars. I am one of the few people stupid enough to have an e-tag and when I deregistered my old car and put my new car on their website, I thought since my e-tag beeped everytime that I still had credit. Well, I got a violation notice which I queried, and bottom line is ... sorry for you your car was not registered EVEN THOUGH THEY CAN SEE IT ON THEIR SYSTEM. And, because I was over the grace period I had to pay the full amount. I left it, but continued paying toll fees. Fast forward 3 years down the line, I get a sms to say that I would be reported to the credit bureau. So I call in to find out the amount and immediately pay over a few thosand rand in Jan, only to receive a sms to say that it is outstanding and they are taking legal action. Phone them to be told that it does not reflect and they still catching up on payments. Then, to add insult to injury, i have a further violation of R11 something even as my etag was being paid during this period. I was then questioned if I knew about it. SANRAL WHY WOULD I SHORT PAY YOU R11 AND A FEW CENTS A FEW THOUSAND RAND BILL???? Enough to make me not pay at all!!
