Sounds like BANIYZ are your old shares if they have not been reduced and you bought them pre RS unless you did the registration deal with the company. Then you need to check the deal you made with the company.
I would call your zecco broker and ask. My guess is that's just their designator for the prereversed shares until they're converted.
You would know if you registered your shares with the company better than I. That doesn't happen by itself.
