MISSING ORDER & UNFAIR BILLING

I am a representative of Avon and placed an order to be delivered to the address where I normally receive my orders. For some reason this particular order went missing and after numerous calls, emails and an Affidavit, I was advised that my order was delivered in Mozambique. One of the consultants telephonically advised that I will be credited on the missing order and a new order will be placed. For some reason the order was invoiced but no credit, meaning I must now pay double the amount. In attempting to call Avon again nobody can assist me. I am not prepared to pay Avon for something I have not received.
