poor service

I placed an Avon order for valentines day on the 8th of February and it was invoiced the same day. I contacted the call centro yesterday on the 14th to track my order and i was advised that they will follow up with the courier company and get back to me and when i emailed them this morning, i get a reply stating that their turn around time is 48 hours! what am i supposed to do or say to my customers who are waiting for their valentines orders in the meantime?!! i had promised them that delivery will be before or on the 14th of February. I'm not sure why its taking so long for me to get feedback as the call centre is well aware that my parcel was sent to Cape Town in error and that's not my problem! My problem is that no one is taking this seriously or at least letting me know when i should expect my order. I have an account with Avon and not with the courier company.
