Scammed By Wedding Coordinator

Last week I received a mass email from our wedding coordinator saying that she has changed her phone number and provided her newest number. I email her back thanking her for the email and asking when we could talk about the timeline for the day of the wedding. I didn't hear anything back. Three days ago I send another email, still didn't hear anything back. Today I texted the phone number she provided and I still haven't heard anything. I started to Google her business and found that in the last two months she has received a ton of negative reviews on Wedding Wire, The Knot, Google, and Yelp. All the reviews say she disappeared after receiving the deposit. I feel like an idiot because the asked for a lot as a deposit. Her overall cost was 800 and she asked for 600 as a deposit. Against my better judgement I went with her because the overall cost was about 300 dollars less than the other coordinators I had contacted. She had great reviews when we booked her in July 2019, now I wonder if those were fake. We paid her through Venmo, I'm not sure how we can go about getting our money back and finding a reputable coordinator.
