You are not banned by us. We cannot help you. 

Try to join a Server over Battlelog, it may give you a reason: http://battlelog.battlefield.com/bf4/soldier/MR_APACHE96/stats/837584560/pc/

If it sais something with PunkBuster you need your GUID which may be shown in the kick/ban reason you get, if not you can get it this way: https://www.youtube.com/watch?v=Pu5yh6gxV6I 

You can check your GUID for a PB ban here: https://www.pbbans.com/mpi/master-player-index.html

If its an Evenbalance Global GUID Ban, then your account is as dead as Evenbalance..
