Times Of India — extra charge by the newspaper agent

Address:

New Delhi, Delhi, 110075

I am residing at St. Columbas Apartments (Flat No A 12) at plot No 15, Sector 7, Dwarka, New Delhi- 110075. I subscribe your newspaper, 'Times of India' regularly for several years. The newspaper is being supplied by one agent in the area.
The Agent has demanded Rs.20.00, over and above the cost of the newspaper, as handling charge. I refused to pay it, consequently, he stopped supplying the newspaper since, 13.08.2017.
I refused to pay the extra demand as I feel this irregular and a sort of extortion. Kindly advise me whether, you have authorized charging extra money; if so, i may consider paying it. Otherwise, I feel you have a responsibility to tame such agents and charge only legally permissible amount. Also advise me how should i get your newspaper at my residence regularly at the approved rate
