Bad customer service

I called in to book a room for my wedding anniversary .... This rude lady picked up the phone ... i booked it and was almost done when she hung up on ...i called back and asked her why did she do that..she just ignored it and moved on i asked her again she said coz she is busy dealing with other customers so i asked to speak to a manager she said there is no manager or anyone there to speak to she was the only person in the entire building and her name was Bongiwe or something ....she said if i want to speak to one of the guest or someone .... i found that very rude ....
