Need advice

I Interviewed with Facebook for a PE role about 5 weeks back . My recruiter was super hard to get in touch with even before setting up onsite. I never got a response without dropping two emails.. on the day on onsite I was told I'll hear about the result in 48 hours, but I never heard back .I followed up every 4 days and didn't get a single response..2 weeks after onsite..I got super frustrated and emailed first initial recruiter who told me that I should hear from main recruiter by EOD. The recruiter still didn't call .called 2 days later and said no decision has been made yet and has to yet go through hiring committee and that I'll have an update within 4-5 days. Now it's been 3 weeks .I've been dropping emails every 4-5 days..not a single response. So basically after onsite, the only time I ever heard from recruiter was when I escalated..I'm really tired of waiting..what are my options..
