Overcharged

My wife accidentally locked her keys in her car. She called Two Cousins to come assist, after waiting 2 hours a guy, opened the car withing 5 minutes and charged my wife R3850. We didn't have that amount of money, he just said that he will wait there for it or call the police. Firstly to charge someone R3850 for 5 minutes work is uncalled for and extremely overpriced. Fortunately my friend could pay for us. What an unpleasant experience.
