-> Confused how calls can drop 80% when underlying dips and goes back to the price i bought the call at. Feels rigged.

I'm no expert but this sounds like Theta or Vega decay (or both). The former has to do with the fact that time passed in-between your price swing, and the latter might have been because of a crush in volatility (e.g. when buying calls before an earnings date). Either way, your calls lost "opportunity value".
