Hyundia 2007 Atos Paint bubbling off

I tried to phone about this matter and just got the run around, then sent an emails to customer service line, got no reply.
I have a 2007 Hyundai Atos color silver, the paint on the roof and bonnet is bubbling off. I have seen the same problem on another Hyundai Atos of same color. is this a factory defect? I have pictures of this if need to see the problem.
