R A Auto

Review: I took my car to this mechanic 7 months ago. He now wants an additional $600 out of no where I told him no we are sticking to our original plan which then he told me he's taking the new engine which I paid for out and putting my damaged one back in the car and giving me my nonrunning car backDesired Settlement: I want my car fixed with the amount he first told me which was $600 not $1,200
