The "debacle" occurred in June. Since June shares have been trading for two separate companies. A stock can't go down 2000%. That isn't how math works.

If you bought before June your shares should have been split 553:1 and the price moved from 0.0005 to .27 cents. And some shares where sold into the market for the new ID at that price.

Any shares bought after June are probably going to be ceased and or cancelled as they don't exist.
