Don't blame the installer for that. The way IPv6 is provided there's
nothing to configure on your host (and there's nothing to blame here either).
You network hardware (aka router), on the other hand, most surely
advertizes IPv6 prefix. So put the blame there or on your ISP.

1) Delicate way of doing it (apply after each boot):
ip6tables -I INPUT ! -o lo -p icmp6 --icmpv6-type 134 -j DROP
2) Hardcore way of doing it (ditto):
sysctl -qw net.ipv6.conf.all.disable_ipv6=1
3) Right way of doing things:
Fix your router.
