So an ebay customer is mad and threatening bad feedback because the ebay estimated date of arrival is today and I hadn't uploaded the tracking. So I did that and it shows it will arrive Mon. In my response to him, do I say I had to get stock from my Amazon account or something? I'm wondering if when he sees the box is from Amazon he'll get even madder and leave neg. feedback. But I don't want to grovel or over explain, or over apologize, either. WWYD?
