Bad Service!!!

I needed to do my learners and get my license. I made use of the driving school being DENVERS DRIVING SCHOOL. Denver being the owner charged me R1200 for 10 lessons which includes him taking you to book and write your learners. At the beginning the service was good he took me to book for my learners i wrote and everything went well. Once i paid him in full for the lessons which is what it says in his receipt that you have to pay for the whole package, he started giving TERRIBLE service. I received my learners in August. He would basically do one or two lessons a month and then disappear.... How are you suppose to learn??? i would send him messages and he even came up with an excuse that all his cars were in an accident so he couldn't complete the lessons i had to wait another month. According to his receipt after three months the lessons expire. It is February now and i still have not completed my lesson.... Denver does not care about his clients all he cares about is money and when you complain he tells you that you are threatening him. I would definitely not RECOMMEND this driving school to anyone. I have wasted my money by paying him, he cancels appointments and is TERRIBLE.
