In my experience, FlyerTalk is a snarky forum of know-it-alls so you won't get any sympathy here.
I would try emailing Southwest if calling didn't work. They might try to make it up to you. I had an agent refuse to help me over expiring points and she eventually just hung up the phone on me. So I got pissed, emailed Southwest and told them I had canceled my Southwest rewards card and I won't be back. I got a response reimbursing me the rewards points. Granted, in my case it was only around $100. In your case, at $3000, the bar might be higher for someone to help you and you might never get that full amount.
