Syndicate bank amalgamation

I currently own around 100 shares of syndicate bank, as per the amalgamation terms every 1000 shares will be allotted with 158 canara bank shares. I have not received any canbank shares in my demat account, what will happen to my existing shares?

It usally takes about 15 days for corporate actions like these and bonus/rights etc to reflect in demat. Given lockdown it might even take longer. Your fractional shares will usually be credited as cash after costs into your bank account.
