Family Credit Ltd. — Long time taking to provide NOC (3 Months)

I am Ranjeet Lodhi it is regarding the NOC letter of below mentioned vehicle:

Registration No. – MP 09 UC 7818
Engine No. – JF33AAG4G12465
Chassis No. – MBLJF33AAG4G12802
Vehicle – HERO MAESTRO (MODEL 2016)

I bought this vehicle from SUKHMANI AUTOMOBILES (opp. mahawar nagar Indore) in June 2012.
I was looking for finance when I was planning to buy the vehicle but at the end I had decided to purchase the vehicle on cash.

Since I had paid full amount to Dealer and said Family Credit Member (which was medium at the time of selling the vehicle) that I don’t want to take Finance hence cancel all the cheque which I was given.
The Family Credit Member, charged me files charges etc . amount which I had paid that time.

Then when I got the Registration Card from R.T.O., Family Credit LTD. was mentioned on the card.
Now I need the NOC letter because I want to remove Family Credit LTD. from RTO registration Card.

For the NOC letter I have enquired to your Office (Man Heritage, near High Court, Indore). They are saying it will take 3 months of time & are not providing any fix date even they don’t have any record or information of me or my vehicle.

I don’t understand when there is not any record of me or my vehicle on your side (on your database) then why this much time it takes.
Three months of time is huge for getting NOC.
Normally Family Credit take 15 days of time to provide NOC.

Kindly help me to provide NOC letter at the earliest.

Thanks & Regards,
Ranjeet Lodhi
