After another round of emails saying that my bag is in WAW I now seem to have a capable person working the emails at the PSL on the case.

Apparently she has written the ground staff several times with no reply and their phone is offline since September 15th due to a technical issue. Mind you, this is Schiphol we’re talking about.
Bag‘s still in AMS and I‘m looking several thousand € of equipment rental costs plus clothes and toiletries.
