I would double check the call forwarding by dialing *73 to disable all call forwarding (immediate, busy, no answer transfer). Many people have it accidentally enabled and don't think they do.
Aej112, we can get to the bottom of this mystery. As crelin suggested, verify call forwarding was not accidentally setup. Remove your battery for a few seconds and reboot if no change. Let me know if you're still having this issue.
