Bloody Hell - 'tis the story of my life (well, not really, but those are the transactions you end up remembering though).
Chargebacks, and the insidious paypal dispute --- arg, now I'm going to vent (let me pre-apologize):
WHY DOES A USER NEED TO BUY POSTAL INSURANCE or ADHERE TO RULES AND LAWS OF COMMERCE when there is such a handy tool for defrauding sellers? The Paypal Dispute is a perfect tool for breaching contract (and it is just that). After all, the user isn't really taking money from you, he's asking paypal to 'act on his/her behalf' - his hands remain clean (think he's the Don, Paypal his henchman). Our listings used to state something along the lines of: 'those that don't insure take full liability for items lost or damaged in transit'. That said, we are covered legally BUT paypal disputes are 100% automatic with absolutely no human intervention. Despite what ppal phone support will tell you (if you have 2 hours to wait on hold to speak to them) the disputes are automatic and if people are looking at them before confirming (the fraud) they are blind & to boot.
If there was even an iota of care from paypal, these things would be greatly minimized as the process itself is not inherently flawed (it's paypals 'hands off' attitude). It's just so aggravating that a user with -1 feedback who will often openly admit their guilty-mind can use this 'tool of protection' to bilk a seller with 99.9% feedback and 4000+ happy clients!
I do realize the 'bad users' are in the minority, however, it's not really them my frustration is with (they are and will always be part of the world), it's the companies we sellers pay that are allowing (I'd argue almost encouraging) their resources to be used to defraud us!
Arg - to be at the whim of the monopoly...
