#germany-reporting

Lost everything to a fake TradingView crypto app from Cambodia, what are my reporting options?

i feel so stupid and broken right now. i met this woman on instagram, she was super charming, seemed really genuinely interested in me, we talked for weeks. eventually, she started talking about crypto investments, specifically this 'amazing' platform that looked just like TradingView but was apparently some special version. she even helped me set it up, giving me links to download it from some app store thing that looked totally legit. i put in around 15k EUR, slowly at first, then more when i saw the 'profits'. when i tried to withdraw my money, suddenly there were fees, taxes, all this crap. now they've blocked my account and she's disappeared. i realized too late it was a total scam, probably from cambodia judging by some of the numbers and language quirks i saw. has anyone dealt with something like this? who do i even report this to from germany? i've tried my local police but they didn't seem to know what to do.
