I got a call from this number too, it was on my cell phone, but I didn't answer it. I don't give my cell phone number out either just for this reason! So I don't know how they got my number!!
They have called me at least 5 times in the last week. No message, no anthing. I called back and got an automated voice gave a bunch of options. I pressed 1 to "cancel your subscription." SUBSCRIPTION TO WHAT?!?!?! then it said "are you sure you'd like to cancel? You will be missing out on great benefits like vacation getaways, new ipod or ipad! Press 1 to keep your subscription or press 2 to cancel." I pressed 2 and got "thank you. Your cancelation may take up to 7 business days to be completed."
Isnt it illegal for them to not say what business/organization they are on/with?
