HB stocks not showing up in holdings

I have purchased HB stocks on February 14th 2018 and from last few days, am not seeing HB stocks in my holdings in kite3.zerodha.com. I have been called to customer care many times but there is no proper response.

I heard that HB stocks are not trading now and some demerger happening. What is the status on this? and how many days will it take to start trading again and when can i see my shares in holdings.

I hope there wont be any issues and all my shares are safe.
