Someone placed an order against my account number

Someone placed an order against my account number, I don't know how. Doesn't Avon validate details before approving an order? This has affected me in a bad way because every time I want to place an order I have to call my Area manager to sort out this issue. The box was returned, there's no way I will pay for that box because I didn't keep it. My area manager even paid for it just so my orders could be released. Now I'm waiting for Avon to do a follow up and credit me so that I can pay him back and cancel the account , I want out of Avon asap!!
