Avon & Fastway couriers.

I do not understand why Avon keeps using Fastway couriers when they are unable to deliver. I place my orders timeously and then it lays in their East Bay for a week before being delivered to me. Invoices ***0 & ***1 have still not been delivered. Can Avon please use another courier. This is pathetic to say the least. I am loosing customers as they want their good by the 1st. I have expressed that this happens every month and nothing is being done by Avon about this.
