Ace Cash Services, DO NOT Let them access your bank account

I was contacted by ACE Cash Services by e-mail and over the phone. THey told me I was qualified for a $5,000 loan. I had not even inquired about their services but I answered out of curiosity. They got ahold of my bank information and accessed my account without notice. They did not even ask my permission and I never said that I wanted to go through with the loan. The next thing I know the money is in my account. It put my account under investigation. I demanded that they take the money back. I had to close my accounts and start a new one so they didi not have my information.
