I filed EU261 after experiencing a mechanical cancellation ex-AMS that resulted in my arriving >3 hours late to my final destination. I filed it via DL.com complaints page because that is where the EU261 information page on DL.com directs to. This was almost 4 weeks ago, and I have heard nothing back. I have PM status.

Is this really the current response time? Or is DL just ignoring me to avoid having to pay out? Is there a better way to file this and get a response?
