I have received several messages on my Airtel prepaid mobile "Thank you for choosing Hello Tunes. You have been charged Rs.30 for 30 days", "Your airtel friends chat service has been renewed" and ""You have been charged Rs 15 Your Hello Tune has been changed to TERE BIN. To hear your hello Tune call 57878" even though I have NEVER applied for these so called "services". I emailed them but have not received any response. I had also applied for DND service but I still get junk messages from Airtel, property developers and others everyday. This company has no ethics. Airtel is clearly out to steal from their customers. In any developed country, they would have had a class action suit filed against them. I would be interested if any law firm or activist citizens would like to take up this cause against this company.
