Who called from 3012444856

I answered a call from this number but there was silence on the other end. I said "hello?" several times before the line hung up.

i got a recorded message

stop calling and dont say anything

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?
