Cause cervini sent a bumper with a bump the size of a golf ball.. Told us to cut it take a pic email and then they would send a new one which they did !
Ehhhhhhhhhhhh....... Took 2 months for them to respond to my bombardment of emails.... ! But they finally took care of it... I was gonna smear them if they didn't respond but they eventually took care of there side of it ..
