Shares gone missing

Hi folks,
Back in 2016 I bought 1700 shares of WFL for around $1500 at an average of $1.486. As you know things went south, but I held on to my shares.
On June 10th I realised that them shares were not longer in my portfolio.
According to my broker: "the share registry for WFL (Automic share registry) sold your shares as you held an unmarketable parcel (value less than $500)".
How is this even possible? I did not gave my approval for this to happen. Is this how you reward your long term shareholders? 1700 shares at 5C are still 17₩₩ shares... What if I buy $1 worth of WFL tomorrow, they will sell it because it's an unmarketable parcel?

Cheers
