None audible

Gee I wonder who it is? LOL

We have received about 15 calls from this number.  The caller ID says "Delivery Notice."  As this is the Christmas season and we have ordered a few things online, I have answered it three times and there is nothing there.  No real or automated voice.  Nothing.  Wish it would stop.  

probably will deliver more telespamming calls

This number (828-333-5707) can be called back. You may get a busy signal a few times, but you will get through if you keep trying. Took me just three times. There will be a recorded message asking if you want to have your number removed from their call list. Right after the announcement leave your area code and number by entering it on your phone keypad. (If you wait too long the recording will play again). After entering your number,there will then be a confirmation prompt asking you to press "1" to confirm. Wait for the prompt then press "1". After you confirm by pressing "1"....then another message tells you that your number will be removed and may take two business days for it to occur.
