Received several harrassing calls from 949-456-8597. Talks but does not respond to me when I ask them to remove my number from their list, hangs up. Researched and find this is MCI WORLDCOM COMMUNICATION INC
2030 MAIN ST
IRVINE, CA 92614-7219
They have no website that I can find.
I now have a trap on my number with the phone company and their number has been reported as harrassing. Next, the legal authorities will be brought in if I receive any further contact from this harrassing company.
