if only that were true, I'm very cynical, sorry
I had seller protection, sent item recorded delivery, to verified address, item was signed for, feddback was left by both parties and then 'the nice' person did a chargeback, paypal gave the runaround for months, until I lost my temper phoned them and told them to take me to court for balance outstanding as the chargeback meant I had gone into the red and I was determined I wasn't going to pay them for their negligence.
IF you ever get chargeback follow the email channels first, then go by phone and speak to a manager not the floor staff, no offence meant but you still get a runaround from them.
If no joy tell them to take you to court or you'll take them if your account hasn't gone into the red.
Paypal really should sort themselves out, they make their money from sellers fees etc.
