a-1 Cash advance stole my money and refuses to give it back and hangs up when you call back indianapolis Nationwide

I was contacted fro a loan i applied for with them. THey then emailed me an approval letter letting me know the terms of my loan. So i contacted them to speak to someone voice to voice they assured me that there was an issued approving my credit score and i need to show some proof of my ability to repay my installment amount. i got the amount inputted in my account and they stole it after they assured me i wouldn't be charged. When i told them i don't want the loan anymore they told me we want more money to process my loan. i told them i want my money back they transfered me to a supposed loan officer who wanted more money before they gave my money back. i said no and then they kept hanging up on me and when they don't hang up they are mean and say you'll never get your money back.
