This number called the office twice today. the first time, I kept getting a female-sounding voice that said, "Hello?" repeatedly no matter what I said in response. Thinking it was a recording, I hung up and the person called back again. This time, they could hear me and asked to speak to the person in charge of our phone company bill (they asked for the company by name, but I'm not going to include it here).

As I have with past calls of this nature, I told the person, "We're not allowed to discuss that over the phone, so please add us to your Do Not Call list."

It didn't help that the caller id showed "CSEARCHAWARDS", either. That doesn't look like a legitimate company to me.

I blocked this number when i saw the caller id, and they still keep trying to call daily and never get through.

They are claiming to be from AT&T and want to upgrade our phone lines to fiber optic had all out information as well as account numbers

These people call every other day claiming to be from AT&T and have to upgrade our services  they have all my info too!
