cancellations of registration

I have cancelled the registration in Feb 2019. But until now I have not got the cancellation order.
I visited department but as per them they are not getting the option to cancell the registration.

whether my registration will be suo- moto assume to be cancelled after 30 days?
whether I will have to file return untill the cancellation of registration is confirmed by the department?

kindly solve my query?
