A) Putting your phone number on a forums site isn't the smartest, perhaps create a Skype account or use the direct PM on MPGH.
B) You said you would like to do this without getting banned, that is the risk my friend. If you want to "hack" you need to be willing to risk things, (i.e your account)! Even if a tool says it is undetected does not mean it is safe and will not be detected, it just means that it hasn't been detected yet.
C)
Activision, Infinity Ward and Treyarch have been greatly improving their security with the games they are releasing so making a modification to the game's files is virtually impossible for the newer games. Most of the mods you are seeing in game such as aimbot, infinite ammo, god mode, etc., are done by using real-time editing tools. I am guaranteed you can find one for Advanced Warfare but this requires system modifications. For PS3 for example you would need a custom firmware to be able to connect the real-time editor to your system and to your game.
Hope this helped... somewhat.
