After the meeting, the recruiter is a somewhat worse option for you than a completely random recruiter pulled off the block, because they've failed in a simple task. Maybe for a good reason, maybe a bad one, but until such time as they explain their good reason they are below par and you can have no confidence in them. "Interested in you" plus "untrustworthy" still adds up to "bad".
If what you want is to speak to a recruiter, I would say either wait for the next one to come along, or else use whatever contacts you have (not current colleagues) to approach a recruiter who specialises in whatever you do.
If what you want is not to lose what seems like a "free opportunity" to speak with a recruiter without seeking one out, then forget about it. It's gone. There will be others. This recruiter might contact you again to apologise, or a different recruiter might contact you in future, but anything you do now to chase this particular recruiter, having already left multiple messages, is recruiter-seeking energy that could be better spent chasing a different recruiter who's never stood you up.
If the recruiter does call and apologise and offer you another meeting, then you should seek some small proof from them that they value the opportunity to meet with you (a show of "good faith", or "commitment"). For example, you could ask them to send you some job opportunities they believe suit your abilities and experience as described on LinkedIn. If they send you a load of generic keyword-matching rubbish, indicating they don't really understand your business or care to, then be ruthless and tell them you don't think they can help you. If they do reasonably well (judging them in view of the information they had to work with, and the fact they haven't yet asked you what directions you'd like to go), agree to meet them, they've proved they actually do want to put some effort in and that they have the capability to suggest suitable roles.
Also bear in mind you might well never hear from them again. It can be frustrating when recruiters just drop all communication and never reply to your last message, but fundamentally it's part of their business for many of them. They have a lot of jobs and a lot of people in the mix, it really doesn't hurt them if any one job doesn't get filled or any one person doesn't get their help finding a job. So the ones who don't care about their personal reputation will chase whatever seems best this week, and ignore everything else. Don't feel as if you've lost something: such a recruiter is basically just a switchboard operator anyway, all they'd ever have done for you is help you search job listings.
