Advantage Auto Collision

I left my car for repair . Sergey the owner gave me prise 300$ for the job . Few days later he calls me to pick up my car and tells me that now it Is 500$ . I said ok. I came to pick up my car before anyone gets to the shop and I see my car on street with unlocked driver car ( and he charged me 700$ for parking inside his place from my insurance ) . 2 hours later his secretary calls me and demands money for parking no later then today and she said if I do not have money by then she would call cops on me . Horrible people and horrible service . And when you pay they do not provide any paper work . Stay away from Sergey and his auto nightmare company
