Idea Cellular — Charges on Data Pack Proration

Address:

Visakhapatnam, Andhra Pradesh

Hi, My mobile # [protected] and I am using the Idea Post paid connection for the past 4 years. This month, I got my post paid bill as 2565.15 which is very huge while considering my usage. On checking the bill, I found 1653.24 as "Charges on Data Pack Pro-ration #". What type of charges are these. On speaking to customer care on 12345, I didn't get any appropriate response regarding that. They simply answering like "you might have done that", "you might have completed the last package" and so on. No clear explanation on that. If they had provided an option to change the Pack as and when needed, then why are these additional charges. While changing the pack also, they haven't notified me about the additional charges I need to pay. The additional unbilled (as per the alerts) data usage that I had done on my pack was Rs 204. Then how come they charge Rs 1653 on changing the pack.
