payza withdrawl thru fraud , Internet

he following person  Marilyn Ayers (machecker111@hotmail.com) withdrew $250.00 from my bank account without my permission or authorization. Payza is supposedly researching this but it has been two weeks and they will not respond to my inquiries. i do not know this person and did not order anything from her or sell anything to her. i cannot afford to lose $250.00. if I had ordered something and did not get it or something like that I could understand but they allowed this person to steal money from my account. I thought everyone that used payza had to be registered with them and verified with them. I did not give anyone my password or access to my account. My payza email id is out there in order for me to make payments and to recieve payments so my payza email id is not a secret. i do not know how they can allow someone to access my account and wonder how many other people have lost money
