Paypal has been decent for me. However, getting hit with a 4 month old chargeback is crazy, espically if you followed all the correct steps. In the retail world, when a merchant uses a creditcard authentication service, certain steps are followed, which in turn, if followed correctly, bascially prevents them from issuing a charge-back. Paypal should take up this practice, or not use it at all. BTW, the retail "world" i am talking about, is Circuit City, the biggest electronics store in the nation.
Customers, or Circuit City when following policy, DO NOT get hit with bogus chargebacks, because we carry to much weight for that to happen, perhaps Paypal thinks that alienating a single customer is less "pain" than dealing with the problem???
