I receive about 5 to seven calls a week from this "company" for the past eight months. Although Level 3 Communications does indeed "own" this block of phone numbers, they re-sell this number to Global Crossing. It is one of Global Crossings clients that own this number and Global Crossing has not been helpful in stopping these phone calls. I was told by Global Crossing to send an email to "
[email protected]" to ask to be put on the do not call list. But this has not worked. I would suggest calling the Level 3 Security Team (1-877-4LEVEL3) and reporting this as some one violating thier terms of service. You can also try calling Global Crossing (800-800-1170) Customer Service but they have not been helpful at all.
