HT Media — paper not delivered against advance payment subscription

I booked 15 months subscription of hindustan times for rs. 899/- paid in advance. But from day one i didn't receive more than 20 papers in a month.in this way they just deliver paper for only 10 months whereas received payment for 15 month
I call numbers of times to their local representative but no improvement in delivery. Now its became s routine to get only 4 days in a week. When i did not receive any resolution i write to customer care and request them to ensure regular delivery of paper but again no resolution. After that i ask for refund of money but neither they refund my money nor deliver the paper.
Isn't is cheating with customers by using unfair trade practice?
