You should have gotten a vial, yes. I'm working on the ring V changes I mentioned last week. There was a hangup on the scripting side that delayed them from going in with the patch.
If you have a Newport Captain's Insignia and didn't get a vial, feel free to petition. Mention that Xeldan requested you to petition to have your Counter Agent Vial restored. I'm really not sure what would have kept you from getting the vial other than both your bank and inventory being full.
