Doesnt teach their students the correct way

My wife has been using Amelia Driving School for the past few months, in the beginning they picked up my wife, they would let her drive an hour then they drop her off, three weeks almost later I am complaining with my wife why she isn't learning with the school, we paid them a substantial amount of cash. Then they have issues, then you see them coming again. then again they stay away until I complain to my wife why she isn't learning and so it went on until I told my wife if they aren't gonna pull up their socks, I will go elsewhere and let my attorney handle them. eventually they started picking her up more regularly. My wife then spend almost R8 - R 10 grand on them for everything (Still waiting for calculations though) but roughly in that area and she received her licence. the very first day I drove in the car with my wife after she got her licence I picked up that she cannot drive properly and that the basic things she is struggling with. I contacted the school and had a long discussion with them and they just made out the problem and said its me. How the F did you get to that. Mickey then said, let your wife drive alone and you will see a new person driving. so I tested it and a friend agreed to drive with my wife to see how she is driving, MY WIFE THEN WROTE OF MY CAR and the only response I got from AMELIA was, speak to mickey. How the hell did you manage a pass, she cannot do the gears, she cannot regulate the petrol, she cannot go around a circle without letting the car die. YOU clearly ripped us off and I will not leave this here. She wasn't ready and even you know it.
