Paint Over-Spray review: Over-spray on my pickup truck 1

I am staying at the KOA campground in Pendleton, Oregon since 2014. On January 18th the KOA campground workers with their manager Jon sprayed with spray guns a wagon that is staged next to my 5th wheel, they also sprayed a wooden fence that is part of my site. On January 21st I washed my truck and noticed spots all over it. I took it to Pendleton Auto Body and they told me this was over-spray. Since this is a brand new truck I didn't want the paint to be further damaged. I took it to A Cut Above Detail in Walla Walla, Washington and had it fixed. This cost me out of pocket $1415.69. The owner Derek also told me that this was caused by over-spray. I spoke with the KOA managers Jon and Kana and they are refusing to accept responsibility and to reimburse me for something they caused. I also need to mention they showed no remorse or empathy and also no accountability.
