So long as your most recent proposal reflects the resolution you want i.e. a refund in this case and the vendor does not make a counter proposal then when the resolution period expires an admin will adjudicate. That sometimes takes another few days after the RC period runs out though, please just try to be patient, hopefully you will get your refund soon. And hey look at the end of the day you at least have a resolution center for the illegal drugs you bought on the internet where you can request a refund, a delay really is somewhat of first world problem in my honest opinion
