Tata Docomo — Fake charges added in monthly bill

Address:

411043

Hello,
I am regular customer of Tata Docomo. I am using post paid card since last 2 year, 1st year they provide proper service. After 1 and half year they start adding fake charges. Every alternative bill they add Voice Portal charges with number as 54321. They did not mention duration of call(time in sec ) only unit of call with out any detail only charges of 179Rs.
It's kindly request you to take strictly action against such fake charges.

Thanks & Regards,
Common Man of India.
