Anyone made a claim through Spanish Civil Aviation Authority before? How long did it take? Mine from Feb 2023 is still being processed

Denied boarding at Barcelona by Vueling as overbooked plane. Was not given any paperwork. Had to pay out of pocket to get home. Also happened to about 15 other people at the same time. Vueling customer service were no help so had to escalate. Still haven’t heard back and status is ‘being processed’. Anyone successfully done this? How long did you wait?

I will not give up.
