I am using Airtel Mobile No. 9872596909. I have been receiving messages from 58888 and 54321 daily for which the company charges Rs.1/- for each/daily. There is no option to talk to customer care executive in 121 and 123 toll free service. I have no idea and way to stop these useless messages that cost me daily. These messages should be stopped with the initiative of higher customer care executives.
