This not a question about technical tips & tricks but about hopefully receiving some tips and tricks about how to finally get proper support from Booking.com. Some questions never get answered by the support department, I really mean never (besides that they have forwarded the request to "a specialist" who never reacts at all). Our account manager, who I posted the same questions to) couldn't care less.
Is there a department where I can file a complaint about this? Or any other trick how to finally receive support for my stil outstanding issues? Anybody knows?
