Pune Traffic Police — wrong e challan issued pnccc[protected]

Address:

Pune, Maharashtra

I was driving my Activa near jail road Pune.
A traffic police stopped me and without any further communication immediately took my photo. I was not wearing a helmet. I told him the reason I was not wearing a helmet because I had medical reasons and I also showed him my medical reports and x rays. After listening to me he said you will not receive a challan and he told me to to. After that I recieved a message regarding Rs 500 challan for not wearing helmet.
Request you to please help me in the situation. I am also attaching my medical reports for reference.
