My experience for paying road tax and car re-registration in Bangalore RTO Kasturi Nagar

It's since a long time I wrote the last post. The intent of writing this post the way it's an utter frustration for me - hence I don't want any other person who is going to change the registration or , paying the road tax for outstation car , should be facing the same.
First if you only want to pay the road tax then you need to have the actual invoice copy, your proof of residence (RTO help-desk told they only accept voter ID, ADHAAR or BSNL bill or water tax) and insurance and pollution certificate.
If you want to manage any lack of documentation you can contact an agent but that'll cost additional money.
The first issue is that it's a government office and the help desk of RTO Kasturi Nagar is worst. If you ask any question they'd be looking as if you're asking some money from them :-)
First tip : try to go mid of weekdays like TUES, WED or THURS - the crowd will be little lesser.
Now for me the challenge was that I am changing or doing the re-registration of my vehicle hence NOC was also required. The required doc inclusive both re-registration and road tax:

• NOC
• Insurance paper
• Pollution or emission certificate
• Form 27 -CMV'
• Form 27 -KMV
• Form 33
• Form 14

From the last form you need to collect SRMB report for tax calculation for your vehicle. The lady in counter 6/7 is so rude she can't help you anything - later we came to know for that you need to go to the Infantry road to collect. And to avoid the hassle you can give 500 rupee to an agent who can collect the report and give it to you.
After that RTO commissioner's signature is required and then the most dreadful part the inspection. That guy is a demon :-)
The whole RTO is willing to play a badminton game where you're the shuttle cork
As my office is on the other part of the city eventually I got hold of an agent to do the thing but if you have some time and patience you may try to do by yourself.
