That...sounds illegal. You should at least have gotten a document in the mail with the buyout details, after everything was finalized and signed. It may take a few months in some cases but they have to send it out.
You're certain you were a shareholder and not an option holder? That is, you had exercised some of your options?
Another possibility, since you said it was an acquihire, is the company actually shut down operations and sold off its assets to the buyer. Maybe in that case there would be no share price to report since no shares were bought? I'm not an expert.
