Idea Cellular Services — Billing related

I have been using Idea Cellular No. [protected] as post paid connection. under some iplan from Idea. At the time of giving connection Idea person told me i can change my iplan packs anytime as per my usage. but he or any other idea person never told me that changing in packs will cost me amount as regular charges of idea for previous usage. when i received bill for that month i was shock as it was more than 2000 Rs. which was not even used by me . I asked about it to idea customer care they told me i am charged as something called prorated or i dont know what they call it . They wanted to tell me that i cant change packs in between of billing cycles. than whats the use of iplan, now my billing amount is 3750 Rs. Now they are calling on the name of police to my relatives and me and telling me that i have been booked under IPC 405 and 420 Aditya birla Group. Surprise when I called back the same number for asking which police station the person didnt replied satisfactory answer and it was charged me Rs. 5/- Per minut. I tried to contact Idea for this matter to solve out but they just reply i have to pay amount as billed, As per my usage My bill should not be more than 400/500Rs. Why should I pay for what I have not used, Why they Are cheating with people like this, And why nobody is doing anything for this,
