Thanks guys for all your answer,. it was just recently surprised morning that when I saw my car it has already dented on my front bumper exactly on the logos place where it was damaged. Anyway just now they fixed it for me from mazda service center. I really don't know exactly if they totally changed my bumper or they just removed it and repair it then fix it again on my car,. It took me 2 hours for waiting including washing,. what do you think guys, do they changed the bumper or they just repaired it?
