I searched on line and found a company who is associated with this caller. i sent and email and got a very quick response via phone.
She directed me to send an email to abuse@level3.com asking to have my number removed. I've only just now done it so can't say if it worked, only time will tell. But it's a start.
Good luck

I keep getting a recorded message from this number. Asks me to press 1 if I am (my name), but I have no idea who is calling me and don't want to release any info. How do I get off this list.

same thing! they f****ng annoying! burn in hell T-Mobile!!

This number calls me at least 3 times a day with a T-mobile automated recording for a person I don't know, it's in spanish and there is no way to get them to stop calling. Has anyone figured out how to get them to stop calling?
