Hindustan times newspaper
Stopped receiving the mewspape

I had subscribed for Hindustan times nearly a year back, for a 2 year subscription. I was supposed to get the coupons which i could forward to the agency dropping the newspaper. It didn't happen for the last 1 year.

Now for the past 1 month i have stopped receiving any newspaper from the vendor, morover when asked they say that there is some issue related to coupons. Needed some help on what is the issue and whom to approach for the same.
