How are we supposed to get clients to buy from a company that can't even deliver on time!

During the December holidays I placed my order on the 27 December 2017 , aware that I would receive it in Jan as our reps had told us Avon was closing. However , my order was placed and invoiced and my SMS stated I would receive my order in 4 working days, those working days have come and gone , I have not received my order, the courier company haven't received it, I have sent numerous emails to queries at avon practically pleading for feedback on my order and nobody has come back to me. My clients keep asking where their products are , not only does this make me look bad , it may affect how many people order from me again. Its unacceptable and I require feedback urgently. Please.
