Yes, you can't charge backs the payments you sent through Moneybookers. It is mentioned in the home page itself.
nothing you can do, once payment is made, is made! no charge backs, this helps the sellers from cheating buyers!
Its a drawback for buyers but also good for sellers as some buyers also do cheat sellers...I also like MB
MoneyBookers transactions are not reversible. No way you can claim the money back. Its gone! Read the TOS.
