it's true. My 74 year old mother got a call from them, several in fact. she didn't answer it expecting it to be telemarketers since they didn't leave a message. sure enough, I call the number expecting to be greeted by a company name, and I get greeted by some indian guy with a heavy accent, and I couldn't understand half of what he was saying. he said it was such and such network, (again, I couldn't understand him) and they cover all the companies regarding the diabetic supplies. when I told him i was on the do not call registry, and that I was reporting them for violation of the registry, he hung up on me.
