SORRY BUT IF YOU HAVEN'T FIGURED OUT BY NOW THERE'S NO SUCH THING AS FREE.
If an insurance representative has told you that other shops don't charge for some process on a repair and this is why they won't pay for it on yours, they are simply not telling you the truth, itís as simple as that. If you don't think so look closely at your vehicle when it is done and see what other item or items they didn't do to cover the cost of the items they did do. Remember also that an agreement between a shop and the insurer cannot be applied to all shops as they may have an agreement that involves referring work for a lower price to a shop which can result in poor quality repairs. Though this practice may not be illegal, it should be inspected thoroughly as to verify that all repairs are done properly and completely. If a process needs to be completed then the insurer must pay for it. The courts have supported this on many occasions as to the cost and reasonableness of a repair.
NOTHING IS FREE, STOP THE MISREPRESENTATIONS
