Good information Mocus but the buyer can still scam you. We even had a PAID and cleared eCheck reversed on us for a service we provided 3 weeks after it had already cleared the Verified paypal buyers bank, and after PayPal sent email to us saying the eCheck had cleared and was now OK to fulfill the order.
It was real simple for the dishonest buyer to defraud us by simply telling PayPal they never ordered it. The crook made-up stories like one of the kids must have done it playing around with the computer. She also later said maybe her husband did it without her consent, or even a neighbor!
The dishonest buyer made up all those lies after first sending us an email and calling us where she asked for a refund as she simply changed her mind about fully using the service after it was already delivered. She lost the first chargeback on the truthful grounds she just wanted to cancel the order after delivery, which win we were happy about but it was short-lived. However, she won the later appeal on made-up grounds of it not being authorized.
I am guessing she heard she could get a refund by later claiming it was not authorized either from a PayPal employee or possibly reading it somewhere that she could by saying the order was not authorized. PayPal refused to take into consideration the first charge back we had won.
There was nothing we could do to fight it. We filed several appeals and had extensive evidence it was all lies what with a very good paper trail and even a copy of an email from the scammer sent before she charged it back regarding her purchase where she never denied the purchase. We also had concrete written evidence she had earlier submitted to PayPal during the first dispute we had won but that proved worthless.
A big problem is when you file an appeal the automated appeals form only permits you to 1. Shipping details and signature for over $250, or 2, You will give a full refund. No other option is available, not even a partial refund.
PayPal seemingly even allows the scammer to keep and use the service and does not mandate it be not used. Like I said before, paypal sucks big time:
http://paypalsucks.com I imagine a scammer could also successfully keep a domain name if they wanted to do so (according to what I read only a physical product needs to be returned).
