Unnecessary ITC placement from AVON

I have been having the same problem with Avon for more than 3 months now.. Saying I placed a second order on my account and there is an amount I should pay.. I refuse to pay it because I did not place an order.. No one can tell me how this is possible.. I have not received any of the products I apparently placed nor did I sign for any products.. I have spoken to more than 10 consultants of Avon about the same matter I have sent the necessary documents for investigation yet no one does their job!! I have spoken to a consultant from ITC as well and yet no contact. Avon keeps sending me messages saying i need to pay and i have been handed over to the bureau and this is unacceptable I will not pay for something I have not placed nor received!! I am struggling as it is to find a job and for Avon to put me on ITC for them not doing their job is unacceptable. I will not leave this matter as it is.
