loan4utoday took 30 dollars from my account twice Internet

I am very angry that this has happened to me. I never thought something like this could happen to me. It makes me sick to know my hard earned money is being taken away from me when I hardly have any to begin with. I live paycheck to paycheck and can barely make ends meet and stupid people find ways to steal money from you!!! Its happened twice now, luckily my bank has been good about it but Im not gonna just change my account number and forget about it. I want someting done about it!!!! They have taken 30 dollars out of my account and ive tried getting in touch with them via email and phone but neither have worked. Im having to leave work to deal with this situation. If anybody has sued these people or found a way to stop them please let me know. thank you!
