RTO India — delayed licence and fraud

Address:

RENUKA NAGAR, PATHARDI ROAD BARABABLI, AHMEDNAGAR CAMP, Ahmednagar, Maharashtra, 414002

Hi, sir
Im from ahmednagar maharastra414001. I gave my driving test on 9th december 2018 and its a long time and i havnt recieved the licence. Even i went to the rto office, nobody is willing to talk.
Earlier they said it will delivered to you with in 20-25 after the trial.
But its now 19 april.
Yesterday i visited rto office, and there was a guy working in rto office said if you want your licence, you have to give rs. 500 more because you gave the test on sunday and it was a special entry.
So we charge rs. 500 as per the rule. You have to pay this money to rto officer. I said, if i get the reciept for it, definetely i will pay if it is the rto rule. But that fellow said we dont give any receipt for it. And if you dont pay this amount we are not giving you, you're licence.
And respected sir /mam plz do help me and help me what to do?
If you want, any proof for it.. I can record the video also.
But i wont be paying bribe to anyone.
Thank you.
Sincere citizen
