So sick of these calls. Just registered for the National Do Not Call List. Hopefully this number is covered by that. But same deal for me - persistent daily calls, never have answered (probably the 6th phone number in my phone listed as "Do Not Answer" because of these kind of telemarketing operations). I recommend registering for the National Do Not Call List if you haven't already to at least cut down on receiving these types of calls.
I started getting calls on my cell from this recently, nothing on the voice mail but silence, try calling back- "not a working number" what the heck is this? alien invasion?
