My Arca-Swiss B1 ballhead needs repair

My Arca-Swiss B1 ballhead has a problem locking and unlocking the ballhead. I need to turn the locking knob for a complete circle and a half (540°) to lock the ballhead, instead of the usual 180° or so. To make the matters worse, turning the locking knob back in the original position doesn't unlock the ballhead.

To unlock the ballhead I need to firmly press on the ballhead, pressing either on the camera or directly on the clamp after unmounting the camera. This situation makes orienting the camera very difficult. It's pretty sad to see this happening with such a highly praised device. Luckily it's still covered by the 3 year warranty, so I'll send it to Arca-Swiss for repair.
