I don’t think so, no.
A common stock, warrant, and unit are three separate types of securities.
A unit is the combination of a common share + some part of a warrant. The unit will always trade at the price of the common share + the fraction of the warrant, or very close; there is no arbitrage possible there.
For your current situation, it sounds more likely that you were owning the common stock, and not the unit. If you were holding the unit, then you would receive the common stock + cash compensation for the equivalent amount of warrants from T212.
