Watchout for Cartract unauthorized deductions

I always have this problem with cartract with all my vehicles I installed cartract! They advertise R99 per month but always deduct more! My last vehicle was sold and for some unexplained reason the unauthorized deductions from my banking account continue with an amount that is more than R400% the agreed amount! Cartract provides the service. They just have to learn the morale and ethical value that it's ******* to con people by their unauthorized deductions. PERCY MARTIN
