unfortunatley, for us, this is becoming all more common.
I have one that is even better for you:
A repeat client emails me thursday morning, needs an order of 28 shirts, (3 color front, 2 color back, on Gildan 8000) rushed for his family reunion, needs to pick them up friday afternoon. Normally i'd say no way, but again this is a great client, who orders frequently for his clothing brand. We accept the order, send a digital mock up and invoice right away, within 10 mins of getting the first email, and get payment 10 mins later. This is all around 930am.
10:30am, client asks to remove 2 shirts, and get refunded, we say no problem.
Noon rolls around, client writes he is just waiting to make sure everyone likes the image he made, says if we don't hear from him by 2pm, to just roll with it. Knowing how things like this work, i email him at 2:05pm, and say "can you please just send me a message saying this is approved", a couple of minutes later, I get an approval.
I stay later to print these, to get a jump start on the order, and start printing these around 7pm. 7:15pm, client calls the shop, my wife answers and he asks to cancel 7 more shirts. We tell him sorry shirts are already printed! He says ok, he figured he'd try.
Next day (friday), job is finished, client picks up the shirts, is blown away by them. everyone feels great about the last minute effort to help this client! Weekend commences.
Monday morning, around 9:30am, client calls saying he got a bunch of extra shirts in the box. That's strange, but I know we also did 4 or 5 tester shirts that were pass-able, and I threw them in. I explained that to him, and he said "oh ok cool, just as long as we didn't get charged for them", which they didn't!
Later that day, client calls back saying his aunt (who I just found out paid for the order), says we charged her for to many shirts, and did not give them the right sizes. While on the phone with him, I check our records, and everything is in order, the sizes and shirts we gave them, match what is charged on the invoice. Client says ok, thanks for checking.
Tuesday morning, I get an email asking to explain why we overcharged them for shirts they didn't order, and didn't give them the right shirts in the first place! I spend an hour typing up a very long and gracious email, explaining everything, giving examples, showing facts and figures, and attaching all emails and invoices. Figuring, maybe i was not explaining myself correctly, or their was some confusion over the phone.
No response, until friday when we get a chargeback notice from american express.
Super cool story, hope you liked it.
