What should I do if Facebook's fake account reporting process doesn't work?

Someone has created an abusive fake account in my friends name. Few obscene/porn images are posted in the album. That account has been befriended by about 300 people. I helped my friend to report those images to Facebook through the procedures that Facebook provides. But the images are not taken down. Perhaps, they don't appear obscene enough for Facebook.

We tried to report the fake account by following the process described in Facebook help pages. While doing it Facebook sends a secret code to users phone as a text message. But we didn't receive that message even though we tried for many times. As Facebooks login approvals are not enabled for my country, Facebook might not have done deals with mobile phone networks of my country. So, I'm stuck without any alternatives. And my friend has to continue to suffer from embarrassment which she did not expect to happen. Is there anything I can do to get rid of this mess?
