So I have mostly wonderful customers who understand that it takes a while to create handmade things. But I've found my first totally irate customer.
Short summary --
Ordered collar for her wedding, states in my policies that it takes 2-3 weeks to ship an item. Shipped her item 1 DAY after the technical 3 week period. She opens a case against my shop, no big deal, she'll get the piece really soon anyway.
Well, something happened between the mailbox and the post office, because the tracking number hasn't updated within a week. So today I get the most crazy, irate, unfounded email from this woman, basically calling my shop a fake, saying that she hopes karma bites my family (what??) and that I'll "get it" for all the "hurt" I've "done to people".
I type an email, telling her that I'm sorry, I don't know what happened, but I'd be happy to FedEx a second piece to her right away, and I'll swallow the costs. Right after I send it, I see that she wrote the most crazy negative feedback that I've ever seen. I get angry, I give her a full refund -- but this means that she's probably going to get a free $150 collar out of it, because unless the package is just totally lost, she's going to get what she ordered anyway.
Okay, now the questions. I closed the case, I refunded her, is there any way I can make the crazy feedback go away? Is feedback like this really that damaging? What's going to happen to my shop? I'm freaking out -- my store is my life, my income, it's everything to me. If this one person ruined that, I don't know what I'll do.
Advice, commisseration, anything, please. I'm ready to throw my computer out the window, I'm so upset.
