Customer care staff are stupid, please teach them phone manners!

I was trying to follow up on a guest booking that left our hotel on route to cape town. Since the guest were European travelers i thought i might assist.. It takes a very long times to phone the customer care line, enter all the details, you get re routed again, you have to enter the details again with the pin number and then you hold on for a consultant (whom is working from home I presume) I did all of this three times just for the consultant to cut the call, not even once did they answer the phone professionally, each time it was simply "Hi" Such a waste of time and effort just to get nowhere! Worst service ever!!!!!!!!!!!
