AS4565 contact

After emailing some of the usual addresses without any luck, I am wondering if anyone might be able to point me towards a contact for AS4565 who could assist me with getting the announcements of some prefixes they shouldn't be announcing cleaned up? Please feel free to email me directly with any clues (or beratement for some obvious place I could have found the information if only I was smarter or tried harder :) ) ... -dorn
