I, too have been getting calls from this number. Quite a few. I would pick up and hear all kinds of background noise, people talking, and no one responding to my hello. I'd hang up, I'd let the machine pick it up, naturally no message. The day before yesterday, I answered it, and a woman calling herself Amanda from The Diabetes Network (we have NEVER had anything to do with them) responded. I literally reamed her a new one, I cursed her out and told her NOT to call back, then I hung up. YESTERDAY they called AGAIN (this is like the 20th time) and this time it was THE SAME WOMAN using a different name! I asked what it was all about (very politely) and she said they were calling all medicare/medicaid people who got diabetic supplies. I responded "well dear, from what I understand, you were told just yesterday not to call this number, that you would be reported, so now I am asking you very politely not to call here again since no one here fits your criteria", now remember I spoke to her just the day before, VERY nastily! She said well I am the one who will remove your number and we will not call again. I responded, please see to it that you don't call here again as I have the number and will report it to all appropriate agencies. let's see if they call again......I'm sure they will.
BTW The Diabetes Network is located in New Mexico....number generates from Maryland
File a complaint here. These calls will not stop, no matter if you pick it up, let your machine take it. And yes, this woman I dealt with was quite nasty which is why I told her off. THAT didn't work, she called back again so I've just filed a complaint. If everyone does this, they will track the number.
Good luck
