Wavy lines after rocker panel repair

[Irpilot]

Hi I was wondering if anyone can post a pic of the rocker panel where the rock guard line is? I just had our model 3 repaired for a dent in the rocker panel and the line that's goes across the whole panel is all wavy. We left the car so they can fix it again and they called back and said they all look like that. I don't remember the line being wavy before the repair. They did both sides so we have no way to compare before and after. Any pics would be appreciated.
