Hindustan Times — vendor asking for extra money even though i have yearly coupon

Address:

Ghaziabad, Uttar Pradesh, 201010

Hi i am a regular customer of hindustan times from over 15 years. Last year i had purchased yearly coupons for hindustan times and hindustan (Hindi newspaper) and now my vendor ask me to pay 30 rs extra every month.
When i asked for the reason he told to contact hindustan times directly. I live in vaishali sector 1, ghaziabad and every month i have to though same argument with my vendor.
Has ht has increased the price for yearly subscription? If not then pls take action on this. I have seen my vendor taking extra money from many people in my locality and this is just wrong. The vendors are misusing their position, i fear that one day he will stop distributing newspaper to my house and because of same reason many people are paying extra money to the vendor.
