Calls me every week for a while then stops for a couple of weeks and then starts up again. Some times 3 in one day. I answered it once. No one there. I decline it on my iPhone now because I don't recognise the number and they never leave a message.
I have received 10 calls since January 10,2017 - When the call was returned - there is an auto message that all agents are busy; however if the call was received in error, press 1 to be added to the Do Not Call List --- this option does not work!
