Caller identified herself as Cox Communications. She knew what service I had from Cox and wanted to sell me more service. I asked her where she was calling from and she said Ohio, but, the call could be routed through offices in Las Vegas or Arizona. She asked me for my telephone number and when I told her I do not give out personal information to unsolicited calls, she hung up on me. After struggling through their phone system I talked with a gentleman at Cox that says this number is one of their telemarketing numbers.
