[Resolved]  Idea Cellular — Extra Charges in Bill

Address:

411009

This is in regards to my mobile bill for the month of March 2017, where i have been charged Rs. 1300/- for data on prorata basis.
I have spoken to the customer care executive but i am sorry to say that the response was very arrogant. I have been charged some 1300 rs for data usage on pro rata basis because i have changed my plan from 399 to 499 in between (as per their customer care excutive).
I had received a call from Idea cellular itself that if am activating a 3g booster plan for every month then its better to shift to our new 499 plan which will be beneficial for you. She explained me the benefits of data and unlimited std and local calling for this plan, so i agreed to shift to the new plan. But the prorata charges was never told and explained to me.
If i am having a sufficient unused data balance on my mobile then how can they charge for data usage ??????
Pls Help
