Care.com Internet Fraud, Scam Internet

I recently got on care.com to be a Nanny/Babysitter and I was contacted by an "Amanda Patrick" who wanted me to be a nanny for her disabled son. She sent me emails and texts for about 2 weeks finalizing our work schedules and things I would be doing for her so called 5 year old son Cole. She proceeded to tell me she was living in Miami, FL and was moving to my area pretty soon and needed a wheel chair for Cole. She was going to send me $350 in advance and an addition $2200 for the wheel chair. I recieved the check and like all scams it bounced and I never heard from her again. I contacted care.com plural times to inform them that I was scammed through their site and lost all my savings due to a phony. They told me there was nothing they could do and that I was on my own basically, so i'm reaching out in hope that people will be careful and someone will take action. My name is Queen Mobley I am 22 years old and I lost everything I have thanks to someone fake on care.com preying on innocent hard working people, I live in Lexington Park Maryland.
