Statements for non ELSS mutual funds

I have invested in some Mutual funds through coin and I keep getting mails from AMC about them sending a statement in some time whenever I buy any fund. But I never receive any statements whatsoever. Is there any way to get the official statement from COIN or from AMC site so that I have a solid proof of my investments. I have seen my investments on CAMS site but what if I want to exit in future and Zerodha is shut down? How will I get my funds then?

All your units are safely held in demat mode. You can register on CDSL easi to download your holding statement.

None of the zerodha users get the statement on their mail then? I was worried if this is case is particularly happening with me.
