Bakwena Toll Roads
Wrong Toll fees!!

I have been using e-tag on the Bakwena highway for a few years. In August an amount of R320 was debited on my credit card for the use of the Carousel Toll mainline. According to the website the maximum toll fee for a heavy duty vehicle is R138. I drive a Toyota Hi-Lux and do use a trailer, but surely not for a toll fee of R320?
I am destroying my e-tag with immediate effect.
