Avon get your **** in order I want my order or all the money back immediately

So I'm a new agent I placed my order received an sms on what to pay I made the payment then I was told it's wrong I made an additional payment and to date no delivery no response whatsoever from Avon. My clients wants there money back but Avon says nothing they just don't care. This is unacceptable it's been a month already we going into a new month Saturday and this order is for March.
