I'd be very surprised if they installed the wrong belt twice.
I don't think they installed the wrong belt; your problem is probably not the belt; I don't think a torn belt would make your car shake (although I could be wrong). I'd be asking your mechanic to check your tires, axles, cv joints, struts, etc
You may want to have your car inspected by a different mechanic.
