How can I delete a call left in my voice mail but doesn't ring just a hang up from a block number ty Gail

When you call your voicemail, while you are listening, press 7 to delete.

If you are using the Voicemail app, long-press the Voicemail message and click delete.

When you block a number, it just sends all calls from that number to voicemail. You can't prevent a spammer from leaving a message. You delete the spam voicemail the same as you would any other. As @Pianodude58 said, if you dial in, just hit 7 to delete it. If you use a visual voicemail app, just long press the caller ID and delete it.
