Since Komperdell is Austrian and their website doesn't seem to list a "contact us" who do I contact if I have a problem with a trekking pole?

Equinox (Trekking)
1307 Park Avenue
Williamsport, PA 17701
Tel. ++1-717-3225900
Fax ++1-717-3220746
Have any of you tried to contact them, if so, who did you talk to about perhaps warantee service?
