Vodafone India — Removal of my lifetime discounting suddenly

Address:

711101

While porting i was said that in plan of 375 i will be getting lifetime 200 discount. But suddenly from last 2 month they removed the discount and charging full amount in my bill. When i asked there representative over call about the same, they are saying that might be sales team have removed the discount she don't know.
Such a big telecom company cheating people with fake discounting plan just to increase there user and then suddenly making us helpless by saying that they can't help in this regard.
Hame on vodafone.
I will raise my voice against this act on all the forum.
