That suxs. Two words for you. CHARGE BACK. Contact your bank card people and tell them. You'll be relieved of the bill and let them pursue the thief. It may take a month, but if it's not over their set dollar amount, there is usually no investigation. BOA has a low limit however, 25bucks I think.
Let them handle it, you get NO WHERE with the post office or trying to deal with customs.
That certainly sounds like a great idea. But as someone who works in receivables for a multi-billion dollar corporation that accepts all charge backs allow me to give a quick run down of what happens when a charge back comes through.
First the charge back is processed,, usually systematically and the payment is reversed.
But that invoice your payment was intended for and paid off,, well it no longer has a payment so now it has a balance outstanding, that is usually past due depending on when the charge back was processed.
Next that bank acct/credit card that you processed the payment with, is now blocked across ALL of our billing systems (we have dozens of services we provide and now your payment method is restricted across all of them)
And the actual account you processed the charge back on, is now restricted to cash or money order only. no more bank or credit card payments on that account for atleast 6 months.
And that invoice that has the balance outstanding now is handed off to our outbound collections teams assuming it's past due, they're calling and sending letters to get payment. Additionally since your last payment was "no good" (ie reversed) your going through collections alot faster than the normal account would.
After a short time the outstanding invoice has gone unpaid and is handed off to an outside collection agency and being reported on your credit report as delinquent/unpaid.
Depending on the frequency of this (charge backs) you're now flagged in our system as a customer with poor payment history and probably can't open any new accounts, or if you can will likely have a large deposit owed and be required to pay off the outstanding balance first.
Also depending on your bank and various other things, they may not exactly like doing business with you if you're requesting charge backs all the time. After so many times it starts to look more like fraud then a customer who got screwed over.
If you're fine with all of that then go ahead and have your bank or card issuer reverse the payment.
My suggestion would be to contact the vendor directly and advise them of what happened, don't start trying to talk down to them or ream the a new one, it'll get you nowhere. See if they'll credit the invoice in question and reverse the payment themselves. Be firm in your request but don't start demanding, again it'll get you nowhere.
Obviously this is only how one corporation handles this, it varies from business to business, I've got no idea how FT would handle the situation. But i just wanted to point out that processing a charge back isn't some magical way absolve yourself of financial responsibility. i often get customers who tell me they'll process a charge back if i don't do X Y or Z, as though it's going to scare me. Generally it just creates more of a headache for the customer than anyone.
Just my .02
to you,
Don't think I ever gotten a bigger vape headache than watching their damn defense attempt to play.
