I have received multiple calls from this number and several others all in the space of 1 hour. The times I did answer only an annoying beeping sound was audible. When I would just let it go to voicemail it would leave the same sound as a message. I have tried to find out what company it is but that information is not available for free. Here are all the numbers that called me: 706-544-5225, 706-544-5211, 706-544-5212, 706-544-5220, 706-544-5218, 706-544-5221, 706-544-5223.
I even tried calling back one of the numbers to get them to put me on their "do-not-call" list but it just rang without voicemail or pickup.
