The guy they sent to my house was very nice (Kevin) He replaced my sons power steering pump on his car on 9/17 a couple days later on 9/19/15 I called Mobile Mechanics because the car was making this grinding noise again to see what they suggested I do. Still no call back as of today. So my son took his car to pep boys because of the same noise as before and they said it was only because he didn't let it idle. My complaint is customer service stinks if a customer calls a 24 hour establishment they should get a call back what if he were stranded somewhere.
