I need details on how to pay back the loan

Hi. I am first time user and got a 100.00 payday loan from cmg group a few weeks ago. I need to kno how much and when (cause it was supposed to be today) my loan will be taken out of my checking account. My payroll check was put in today. I need details on how to pay back this loan, as I have heard horror stories about these payday loans.I would like to pay it off , and I thought it would be automatically taken out today. Any help you can give me will be much appreciated, and I will definately use your services again if this first loan goes well. My email is email address removed as per forum rules - Mike and my loan was taken out a few weeks ago.
