Koshmechanic very bad

Please don't use this machanic, you pay for 4 shocks, he only does 2 and hope you never look. But we did. Phoned him and he was very rude and told me that it was not necessary for the back shocks to be replaced. But he took the money for all 4 shocks but only replaced the 2 front shocks. Now when I asked for my money he got a lot of problems he can't buy food for his family and swear at me
