Let Me Pay my Own Toll Fees

I recently hired a vehicle from Woodford. I'm tempted to give 5 stars as I received excellent friendly service from the staff and cannot fault them. However just two concerns. The vehicles in my opinion are well polished and on the surface you cannot see some scratch marks. It's only the following day or two when the polish wears off that you notice little scratch marks which we didn't notice upon taking possession of the vehicle. The okay thing is, as long as you notify the office, you are not charged which is good. The second issue I have with Woodford is the payment of Toll Fees. I wanted to swipe at Marianhill toll plaza but the green light comes on and the boom lifts allowing me to continue. It's only then I realized there is an E Tag gadget on the windscreen. That's fine but I get charge R50 handling fees and R11.40 VAT. This is so unfair as I'm at the Toll Gate and have the monies to pay. Why must I be charged and ********** for something that's no fault of mine, when I'm at the gate and can easily pay it myself? I can fully understand if the customer fails to pay toll fees. But, Why would someone in their right frame of mind pay an extra R61.40 for something that will only cost them R26? I'm asking myself the question. Is Woodford using this as a cheap means of enriching themselves at the expense of the customer? One customer may look at and say it's only R61.40 that's minor. But for Woodford it can mean mega bucks. Let's do some maths. If Woodford hires out 1000 cars per month countrywide that effectively means R50k minus the VAT. Think about it. Maybe this is one for the Competition Tribunal to look at.
