I programed my "voice mail message" on my LG800g and immediately set up my password and rechecked it and it worked. If I hold the key down to listen to my mailbox messages and enter my code it tells me that is an invalid code and hangs up. If I dial the number to access voicemail (1-305-972-8996) .when I punch in those numbers to collect any voice mail it's like my key pad doesn't work or isn't connected to anything. How do I fix this situation?????
