Hi, there i made some research if webmoney/wmz etc. payments can be reversed and if payment can be chargeback and these are some quotations i found:

"WebMoney makes online businesses immune to certain scams because transactions are final and cannot be repudiated by the spender which is similar to e-gold or cash transactions but unlike credit card transactions and PayPal which can incur chargebacks" viaden.com
"Unlike other online payment and money transfer systems, WebMoney transactions cannot be reversed or canceled." eHow.com
"It is safe, reliable and confidential. Payments are irrevocable (meaning they cannot be reversed)." AlfainHost.com

Quotation source can be googled. I did not found any other mentioning about WM chargebacks/reversal so am i right to think WM payments canot be reversed and chargeback?
