Has anyone been able to deposit USD funds into their C-CEX account recently? Would appreciate knowing what method you used.

At https://c-cex.com ...
"C-CEX codes let You transfer funds between C-CEX accounts instantly and without any commissions.  C-CEX codes are great way to deposit Your USD to our exchange!  Www.xmlgold.eu, money-change.biz and v-obmen.com are selling our C-CEX USD codes at reasonable prices with lot's of payment options.  After C-CEX USD code purchased You can use it to fill Your account with USD instantly!

The first two of the three links below don't work.  After translating the third one at v-obmen.com into English I still can't figure out how to actually do it.

Thanks!
