If you are a friend, trying to give us money or just want to talk, then leave a message or try my cell phone number. I don’t know who you are, and I don’t know what you want.

You can put a network block on persistent telemarketers, but you need to contact your network provider for that.

Leave your name, number, the reason for your call today and the best time to call you back. I’ll speak with you shortly! ” Your caller probably wanted to reach you, not your voicemail.
