Tata Docomo — regarding wrong bill statement

Address:

Pune, Maharashtra

I am totally 100% dissatisfied with tata docomo customer services.
i have taken plan of 999 monthly rental but after 4 month still i m getting bill of 1149 monthly.
i have raised the request as well from the first month but no action taken so far now.
this is one of the worst service i have ever had from any firm.
every time when i call i get the promise of adjustment in bills.
please do something for customer not for just money
