Vodafone India — Promoting annoying advertisements, deduction of charges for services not requested

Address:

Chennai, Tamil Nadu, 600 053

I'm a subscriber of vodafone (Tsmilnadu circle) mobile services such as 3 g and voice calls.
Recently, i have been facing problems of annoying advertisements provided by vodafone india. Recently some vulgar websites were popping up regularly and complaints were launched with the service provider immediately asking them to block such advertisements. However, no effort seems to have been made or neither my complaints taken seriously.
Yesterday, ie 27/11/2016, a game was installed into my mobile in the name of 'tube world' without my request for such a service and an amount of rs.35/- deducted from my talk time balance.
Similarly, on 9th nov.2016 another game pack by the name of 'skill derby' got installed into my device without my request for such a game pack.
The problems with these game packs are that once installed, we are not able to uninstall the same and keeps popping up every now and then.
I suspect, these game packs are a ploy to collect personal infos from our devices.
Similarly, vulgar websites are promoted by the service provider.
In spite of several complaints to vodafone tamilnadu customer care, nothing has been done to stop such nuisances.
This proves that no proper and adequate security system exists with the service providers.
I request the authorities to initiate action against the service providers.
