Has anyone heard from Khamul?

I paid Khamul for an icon commission back in March after they invoiced me. Since then I noticed they've been inactive on all of their accounts. The note I sent on Mar 25th, 2013 hasn't been read.

Are they OK? Has anyone heard from them?

EDIT April 11th 2013:
Opened a dispute with Paypal after no contact.
