Balo's Tire & Auto Repair The Machanic made unauthorized repairs Chandler Aze

i recently got my car fixed in chandler Arizona by a local Machanic shop . When I first got to the shop I explained the problem I was having with my car , which I already knew because I’ve gotten it diagnose by multiple Machanics . So the Machanic took a look at my car and he agreed with me and also felt I needed a new power steering pump and also a power pressure hose for the leak . He did the work on my car and the next day I picked up my car the next day after that my car sounded worst then it did before my power steering pump would make loud nose and I still had a leak in my car so I asked him did he fix the problem I payed him to do

long story short I brought the car back 4 times the Machanic because each time he didn’t solve the problem the 4th time I brought it back I was so fed up so I asked him if he ordered me a new part and replaced the part he just put on because it was no good the next day when I brought it back and came to pick my car up the Machanic said that I owed him extra money because there was another problem with the car and he fixed and I had to Pay before i could get my car back which I feel is not right because I did not authorize him to fix that on my car
