I need info on prepaid credit cards pronto!?

The banks are robbing me blind. I don't trust them any more. I put money in my account and it vanishes. No explanations.Today, my account just VANISHED. Disappeared. No reason no rhyme! I'm fairly certain I'm not crazy, and I handed my information regarding my account to NO one and NO body.I heard about prepaid credit cards and I need to know if there are any draw backs. Any one have a bad experience regarding them? I need help.
