Consumer Redressal

Vodafone Billing issue-currently sent me demand notice, though no mistake with me.vodafone postpaid number-9962826448.I sent an email for disconnection where i got a reply saying "i should confirm 48 hours before disconnection on the next bill cycle".Since i didn't get any new connection on that time,i didn't ask to disconnect.But without intimating me they changed my plan to "Data only" plan.Hence my bill amount got increased like anything. I mailed vodafone on the issue.A customer care representative spoke to me and said you are charged on prorata basis.I explained detaily and asked why I am not intimated and also i have not confirmed on disconnection. He checked details and said the amount would be reversed.Also i asked "what should i do if i should not be charged further". He told me that i should not be using this SIM further since i am charged for data usage.I stopped using that SIM . But I was being charged for what I was not using.It's the vodafone customer care which misguided
