Avon orders Invoiced and NO PRODUCTS - rep not responding to emails

<p> I constantly have problems with products not in the box but been invoiced. This last box had a hole in the side where a mascara must have been taken out (if it was in the box). I am not getting a response from my rep, so how do i do credit notes if i can not get info about how i must do it? I order at least R4000 - R5000 a month!!!! How many more times do i have to complain?</p>
