This is my reply to them:
The reply from my customer, coz I carbon copy (cc) to him. I got no reply from the supplier:Does that mean that if we have typo error, your production will follow blindly? Why then the bottle didn't come in blue?We admit that we did not amend the colour part when we issue the PO to you. In the future, we will not indicate the colour for every product ordered. You should know by now what colour is for which bottle.
As a supplier myself, I will always call the customer if they order is out of the norm. Just to confirm whether there is typo error or not. Human make mistakes.
Good idea. Meantime, I will email them another bottle colour guide. No reason they should get it wrong again.
