Micromax Mobiles — Not providing promotinal schemes by micromax

Address:

Jalandhar, Punjab

I hav purchased micromax phone model e313 through flipkart. There was promotional scheme stating "get 500 mb per month valid for two. Months on vodafone offer will ve activated in 48 hours on first vodafone sim inserted in micromax phone" so i bought a fresh vodafone sim "[protected]". Its been almost 10 days that i haven't got any benefit. I had contacted flip kart, micromax, and vodafone regarding this. .
No help regarding this has been provided.
