Vodafone India — Excess bill payment

Address:

400064

I had a plan of 699 before.then I changed to 99 plan. I was explained by the Vodafone store executive about plan and payment of 113 with service tax. Now i have got my bill and i have to pay 304₹.

1) I was told that i will get 250 mins local n STD calls, which after bill was just 150 mins.
2) as soon as my bill cycle got over of previous plan i went to change my plan bt they said only after bill generation we can change your plan.so in my bill they have added prorata service charge of 699 plan, which is not because of my usage. Why should i pay it.
3)after they change the plan there is no intimation or message which store person said you will receive. So they have charged me internet charges for 10 gb.

I am not happy with Vodafone at all.
Also when i was using 699 plan there was not a single call from Vodafone recommending me a plan according to my usage which was 1/3rd usage of wat the plan gave me. But when i started 99 plan i hv frequent calls.
