Sadly there is little or nothing this group can do for you.  We would
strongly advise networks to be very careful when maintaining their own
blacklists or with which services they use as stale information can lead
to incidents such as you are expeiencing.  And this is likely to happen
more and more as exhaustion approaches as more and more space is used.

The best advice I can give is to contact the relevant large companies
and inform them that the space has now been allocated to CARNet (with
approriate Whois links etc) and ask them to remove their blocks.  As
with all such things, their networks, their rules, but hopefully the
knowleged that they are losing out on quite a few potential customers
will encourage them to quickly update their rulesets.  If the companies
use services

As Thor mentioned, you may also be able to find out which geolocation
services are being used and go to the source of the problem, but these
may vary on a company by company basis.
