Mahindra And Mahindra — Registration No. New Vehicle

I have taken the fancy number UP16DA [protected]@@6 by paying Rs. 5000 online to RTO, and copy of same provided to the delear for submitting the documents and registration fee to the Authority's.
The vehicle has been handed to myself on 12- Dec-2021, but the approval receipt toward submission of documents for Registration purposes to RTO by Delear (Mahindra Shiva Vaishali Metro / Shiva Auto Car India Pvt Limited) was not provided as on date, it's been 20 days now, pls support and provide the RC approval for my ease and travel opportunities
