Our cable operator charges Rs 250 per month per set-top box but does not issue any receipt. He did not give us the receipt of Rs 1,000 that he charged us for the installation of the set-top box. Also, the operator does not provide channels of our choice and threatens to disconnect the service when confronted. The reception and irregular service is another problem. Ankit Jain This is a case of rampant malpractice by the cable operator. TRAI has issued instructions but operators are not following them. Hence, the authority may consider some consumer-friendly action in this regard. We shall formally appeal to them.
