Non compliance with CPA

I rented a car the weekend of 26-27 September and when I made the booking online they stated that the rental amount was R1596 when I got to *** I had to pay over R7k for the car hire and deposit when the agreement that was sent to me via *** did not stipulate a deposit amount. Furthermore when I enquired about the refund I was told by the refunds department that the rental ijt was over R2k which was NOT the case and they deducted a toll gate fee when I never even used a toll gate on the road that I was travelling this is ridiculous I would never use this car hire again seriously! I want my full amount back which excludes the rental amount that I was told would be R1596 this is pathetic knowing people are vulnerable to needing a car when in an entirely new place is ridiculous to increase costs when you state one cost when making a booking
