how can I give good customer service when they dont give any

I started at Avon in october and placed an order mid october. Ive been waiting for someone to contact me or send me an invoice...anything. 3 November I had to contact the head office which took half a day to find out even who that is. they finaly gave me my account nr and password IN NOVEMBER! my clients are frustrated and dont want to order from me again because I keep making excuses that avon will come back to me .
