Can I still get my money back ?

I was scammed almost 2 wks ago and I have to give $750.00 for they said security deposit for a personal loan that I applied for. They want another 300.00 cuz my credit was very bad, so I told them never mind I just want my money back, and I was told w/in the 10 days or earlier my money will be back, but nothing happen. I did complaint in the consumer complaint website and the BBB. I was very upset and stressed because that is the money for my car payment. Thought people will give me a second chance to pay all my credit/payday loans.
