How to listen the next voice message

So when dial 123 to listen my voice mail, whether they are new or saved, when a message is finished playing, it asks me to some options like replay, forward, message information, delete or save. How do i just go listen to the next message? I dont want to save, and when i listen to saved messages, i dont want to delete. I just want to go to the next one. Why dont they just key #2 as To Listen to the next message? 😣
