I gonna try calling the ISP.
I made a tracert from another ISP and the result is worse:

As you can see now it seems the packet again goes to USA and takes a long path to Argentina. May be my home ISP had a direct link to Argentina and my job ISP hasn't. I'm gonna try to make some consulting to the ISPs but I think that my battlefield2 days are over
