Tata Docomo — Unjustified Bill

Address:

Raipur, Chhattisgarh

Hi,

My name is nitin Thakur from raipur and i am using tata dokomo No. [protected]. I am using 899 unlimited plan with 1 GB 3G plan. So many time i called to Customer care and asked about my data usage but they told me that they can not tell me data usage. i asked that if i used more than 1 GB data than who will responsible for the same so they told me that my credit limit is 1600/- . and when your usage reached this limit your data service will stop automaticaly and you have to make payment for the same.
Now they created a bill of 3475/- and tell me to pay. now they tell me that your limit is 2100 and you have to pay 3475. Please help me in this matters.

Thanks
Nitin Thakur
