Don't worry dear, I purchased my cb in may 2019 and registered it in June. Got my papers back in August 2019 however smart card I received from excise office in February 2020 (I received call from excise office in my local area to collect the card from the office )
Computerized Number plates are not yet received , it's been almost 1.5 years of registration and I am still waiting for genuine plates
They told me that it will arrive by post whenever govt issues in this matter will be settled
