I still not understand why there is network like TATA DOCOMO. its just a useless network special the post paid connections. About the customer services, they only to know how to pass the call to another operate services, they never wants to fix our problem. I still remember, once I am using post paid connection there are many problems like, network, internet and call flexible. whenever I called to customer they never help me for anything they always pass the call to third party to say they will solve my problem but, the result is zero. Now the billing of post paid it is horrible. no words to say about the billing.
Thank you
