As a such, perhaps you have some interesting insights into what might be causing PayPals uniquely poor (it seems) CS record? It seems that the majority of PayPals public CS failures could have been avoided with a minimum of, well, intelligence, training and helpfulness.

I guess being the middle man in a sale / money dispute usually makes at least one people unsatisfied of you ?

I don't know what the hell you were doing then because I've never had any good interactions with Paypal. Ever. Last time I tried disputing a charge when the seller disappeared on me (and several other buyers) I couldn't even get a response from PayPal at all. That was the last time I used it.

FWIW customer service survey results were not bad at all but it was five years ago, I know nothing about current situation, and each market is different.
