Travelio has not returned my deposit. What do I do?

Move fast and move in writing. Screenshot the entire in-app chat before your access lapses — it ends with your tenancy. Then send one written demand, in the app and by email the same day, stating the unit, check-out date, deposit paid, amount returned, amount outstanding, and a seven-day deadline. Ask for one specific thing: payment, or a fully itemised breakdown with dated before-and-after photographs for every deduction. If that deadline passes, file with BPKN and the LAPOR! portal, take it to your local BPSK — which hears consumer disputes without a lawyer — and publish a factual account. In every resolved case in this archive, resolution followed publication.
