        Good.  The attacker is trying to you as a amplifier and
        that is not happening.  That is all one can reasonably
        expect.

        The next thing you should do is ask your ISP to chase them
        back to their source and if they are local to the ISP block
        them by implementing BCP 38 other wise to pass on the request
        to the peers they are getting them from.
