Why some online payment service providers always protect the buyer not the seller?

I think it's real not fair to protect the buyer more, so some fraud activities alwaya happen. For example, the customization shopping on-line service is hard to be protected if someone want to have something customized on-line and then they asked to charge back the payment when they received the item with the reason of 'total different' which is hard to judge who's right because everyone has its own feelings on the custom item. Under this condition, the on-line payment service provider always protect the buyer by sending the money back. Actually i think it's not fair.

 

This is inevitable. All of their money comes from buyers. IF the buyers are protected there will always be sellers. Its the only and widest method of payment processing available with its convenience. if there was a challenger maybe there could be some headway for the sellers to negotiate but in this case, buyers wont return, as long as there are buyers...sellers always will.

 

@TheBankBreaker Well explained.

 

Yeah , i hate this principle from paypal....they should not protect anyone , they should just let the deal be deal....
