I am from Bangalore and have been facing trouble with the TATA-Docomo network for past 1 year. The network is very poor, whenever someone tries to call me they get to hear a busy tone. They boast of having numerous offers but when you call the Customer care they will not have the complete information about query being asked or they just hang-up the call and they charge 50 paise per call too.
I do not understand if the service provided is not good at all they why are they charging. Call drop is a frequent phenomena, while speaking to someone the call suddenly gets blank and then you have trouble dialling again due to poor network.
