Who called from 7073010007

I went to NC to visit family. Soon as I got there, y phone started saying "Call Forwarding" when I'd dial a phone number any number. I have been back for about 3 weeks, and my phonne still would say call forwarding whenever I'd dial any number. I called At&T , and they sent my instructions to disable call forwarding. When I went through the menu, to disable Call forwarding, it listed that If I'm unabvailable, that the number call or caller would be forwarded to (707)-301-0007. I've since turned my call forwarding off and it should eliminate the problem, but I thought I'd report this number and hopefully you can find the owner of that number who obviously hacked my phone so that calls would b forwarded to them !

Mike, no one hacked your phone. 707-301-0007 is an ATT voicemail #. Your calls were being forwarded to voicemail.

I got a voice mail from 707-301-0053?
Do know somebody about this number?

I called this number, noticed it in my call forward settings. A man by the name Mike answered. He told me he is in NC. Weird.

I am not getting any of my phone calls. I took it to an outlet store, but they were almost clueless. One employee had the nerve to joke about it, saying its the cosmos. Well, I dont own a cosmo phone, I have a ZTE.
