Contacted by recruiter, passed initial screening, was told a phone interview would be set up with an engineer. Haven't heard anything back since.

For a little more background, after passing the initial phone screen I told the recruiter I'd be out of the country for the next month - but was willing to schedule and hold the phone interview while I was gone. He responded by saying "Sure, no problem", but I haven't heard back from him since! I sent several messages before leaving (about once every 4 days) asking for an update - and two messages while gone inquiring as to what was going on. I am now back in the country, sent another message informing the recruiter and still have no response back ( a week later). I don't have the recruiter's phone number, and I'm not sure what to do from here. Emails are obviously getting no response and I don't see how else to contact the company. Do I just assume they are no longer interested? How can I contact the company to let them know I'm still looking to work for them?
