WTF happened to GTI?

I had a 100 shares of Graphene Technology. I bought 70 shares at $1.43.. It went down to 0.12 so I was down. I bought 30 more shares at that price to put me at 100 shares.

Today its grapghjet technology and I have 1.666666 shares at 0.12.

Can someone ELI5 what happened?

Thank you, for all the replies. Now I understand. Thank you very much.
