Helderberg Suzuki

We had the misfortune to hid one of these plastic warning sigh nextvto the road with the wind in western cape blew under the car and the radiator and some zircon pipe got damage. Aa pick up the car took it to helderberg and also started the claim through insurance. Fist we got a quote for almost R13000.and insurance paid out say R8000. Then the problems started . 3 weeks later we get told they made a mistake and there is a additional R1300 plus outstanding . To day we went in only to be told again. I say again that the route has jumped t00 R16000 and some thing and we now had to pay in additional R3300. Then my wife received the new quote per e mail stating R1300 plus. So can some in Suzuki explain this to me because every one says pay . Where we come from is the fist quot is correct espesialy if it was paid. The person that made the mistake carries the diffrence. Can some one at this crock place please assist. Extremely bad 👎
