VAT number input
I have received an email from Booking.com asking for VAT numbers to be added to my listing under the finance section. This I have tried to do on numerous occasions but their system simply returns a message saying "This VAT number is Invalid". Has anybody else had this issue? I have tried every combination possible and sent an email to Booking.Com but they have replied with a "try again" message or go to the Community for help. I am busy - very busy- & irritated. I am finding the contact pathway to Booking.com very difficult to navigate (why on earth they don't just have a big red button saying EMAIL US HERE - I don't know, because it would really help). Any suggestions?????
