[Resolved]  Idea Cellular — regarding offers

I bought a new phone from amazon.in during great indian sale that comes with an offer from idea/vodafone in which the user gets additional 1.1gb/day with any unlimited plan of 199 or above.
So, after activating my idea sim in my new phone i also got an sms from idea saying the details about the offer. I recharged my number with 398 in which we get 1.4gb/day for 70 days. Now i was supposed to get 2.5 gb/day since i was eligible for the offer.
But i got only 1.4gb/day as per the usual plan. So i contacted idea. I called them many times but was able to pull the conversation a couple times properly.
Conversation 1: he told me to activate the offer manually from my idea app under the 4g handset offer section. Tried more than 10 times, it won't work. Well in my experience if there's any such offer, it's activated automatically.
Conversation 2: here's the real twist, he was trying to convince me that i had no such offer. When i tried telling that i even received an sms from idea, he refused and i was blank. I mean what could i say if he is stating some useless points.
I am also attaching the screenshots of the offer message that i received from idea and the page where i tried activating the offer.
