There ARE two sides to every story!
This person waited FOUR weeks after he won to pay for his items, and as ALL OUR CUSTOMERS KNOW, You need to pay within two weeks to get our "flat rate" shipping, which costs us a fortune, but which we give both to reward good customers and to strongly encourage them to pay within the two week time frame (because in that time we have auctioned 5,000 items).
But this person chose to wait FOUR weeks and then simply send the flat rate shipping of $11. Our automated system sent him an e-mail saying "we will send your item right out" because, in the past, no one who sent the wrong amount has later complained when we discovered their error and e-mailed them saying "We need X amount of money because you did not send enough".
So when our invoicer discovered this person had not sent the right amount, they correctly sent an email saying that we needed to find out the exact shipping cost, and they would be emailed that.
Now unfortunately, this fell right after we had our major auction, and we have 550 shipping quotes to get. So yes, there was a delay.
Then this person called a short while ago, and yelled at the person on the phone, and after he said "You people are all assholes", she hung up on him (per my instructions) because this happens once in several thousand phone calls, and I do not pay them enough to take abuse like this.
I will now send out the order for the incorrect amount, and this person will never order from us again.
End of story!
P.S. THIS is exactly the sort of situation I added the "Hershenson Help Hotline" for. All this person had to do is call me at any point in this story, and as Holiday points out, I would have quickly resolved it.
