Insurance Fraud?

So if a body shop charges for a new fender and then places a used fender on the car, this is fraud correct? and if the same shop charges to remove an item and doesn't actually remove the item, but also doesn't refund the money, this too is fraud also? Then how come body shop's charge or get paid 12 hours for repair time; only actually use 6 of it and then keeps the difference? Aren't they defrauding the insurance company and their customers out of 6 hours that were never used?  If the average labor rate inside a body shop is $48 per labor hour, didn't they just defraud the insurance company or their customer for $288.00?

Here at our shop we do things different, we only charge for the actual hours required to do the job, materials used, parts required and shop supplies. We don't defraud the insurance company or our customers.  Doing things this way takes a different approach and a unique pricing model that we pioneered and are currently in the process of perfecting.

So in summary, you get more for your money at our shop then any other shop in NC, with the quality to match.
