National Payments Corporation of India [NPCI] — Excess data charges for a V India mobile

Address:

Chennai

Sir / Madam,
I have been using Vodafaon # [protected] for nearly 20 years now,
Recently during in my bill cycle5th feb'21 to 4th Mar'21 - The bill amount rose from 12120/56, When i have raised this with vodafone customer care - They gave this reference number[protected]. and told we will check and do the needful.
After multiple follow ups, They finally told there are genuine charges and they cannot help me in waving off the bill,
My plan is only 99/- + tax monthy charges, I have been paying maximum 120/ per month till Jan'21. suddenly this bill gave me a shock and its very difficult to over come. They simply say we hve sent to you alerts and you have clicked on the alerts so the charges. you have to pay, - But they set my dynamic cridit limit is only 2400/ - I asked them when you have set an dynamic credit limit - why did not you disconnect when i reached the dynamic credit limit, - This would have solve the problem, - That is the reason we have set the credit limit - But they have no answer but simply say i have to pay the entire 12120/ - which is 4 times beyond the credit limit, This phone number is given for all purposes, with no other alternative, I have paid the entire amount for continuity of service, I request your goodself to take this geniune case and get my refund the earliest.
