Rto India — NOC pending to receive.

Dear RTO,

This is to inform you that i have applied for NOC on 21 Jan 2021 and all the documentation also completed with Police verification. One of the agent came to me and said he will support me to get the NOC within a week but till today I did not get it.
He is asking extra 1700rs money for NOC in which I have already given him 2000rs before.
Agent is saying that i have not paid the road tax completely that is the reason NOC is pending, if I could have not paid the tax properly I could have not got the RC card from RTO.
I requested RTO to please help me out in this and support me because I came to native now and still more than one month is over and i have not got the NOC yet.
Attaching NOC details for your reference.
Please support.
I have to get my vehicle transferred ASAP but till today I am struggling.

Thanks and Regards
Amaan khalid khan.
