On their website they have this email: email@example.com
I would try that, before placing a call to Austria, but if your game to give that a try.... ++43 / 6232 / 4201-0. skype or google voice is your friend.
Try shooting them an email, explain your problem and ask for pricing on replacement parts. Be sure to include the year that your poles were manufactured so they know what parts to replace them with since so much can change from year to year on the same model of pole.
I had an issue with my black diamond poles (mouse chewed through the hand strap and one of the tips broke off the shaft) so I called them up and they were able to sell me the replacement parts that I needed.
