Dinamalar — subscription amount

Dinamalar newspaper agent collects more subscription every month. For example the subscription for the month of feb 2018, he collected rs 190/ (One hunderd and ninty only). He said the sub. Amount has not been publised in the newspaper as done previous only to collect excess amount. Are you permit it? I have complained in your free toll number for six month before and somebody enquired immediately and told me to give only sub. Amount. But he told extra amount tobe given as per your willing. Is it correct method of approach? I think you are encourageing this. Many people paid extra amount for home delivery. Pl. Fix the rate of your paper for direct purchase from shop and home delivery
