Dinamalar — Udumalpet Newpaper agent not retuning the yearly subscription cheque and not stopping the newspaper

Udumalpet Dinamalar agent not responding on the yearly subscription and returning the cheque. I opted for yearly subscription, and provided cheque for the same. After a year he is coming back asking that cheque is not deposited. I said that to return the cheque so that i can provide the money provided there. However he is not responding and not returning the cheque, even after multiple reminders and calls in last 3 months to stop the subscription he is not stopping the newspaper. Last year also he didnt collect money on monthly basis and demanded 2500 for the yearly charges. its too high to pay the money in single payment instead of monthly. But there is no complaints department to complain on this, and the numbers provided in newspaper also is switched off.
