Kimberly from AT&T calls everyday to tell me that my internet service has been breached and to call the above # for tech support. I did call the number provided and they asked why I was calling. When I told them that they had called and told me my internet had been breached they said that they had received messages from my computer telling them that there was a problem. I called my AT&T service and was told that everything is fine. I also reported this to them so they were aware that someone was using their company name to commit a fraud.
