Horrible automated response system with days of no feedback to change the verification login number of my property to a new number

Still no help from Booking.com Your service is absolutely horrible. 4 days to try and change my old number the new number to view my bookings. The South African number is not working and cuts of immediately. Automated responses on partner help and emails. Horrible website & app that is not user friendly at all. Treating people that list with them like nothing.
