Vodafone India — Activation of new sim card

I Purchased a new sim card from Tamil Nadu, i have submitted all my documents for it correctly, i was told that my sim will be activated within half n hour. this was a false commitment made by them. later again i contact a person regarding the activation they said it will be activated within 5 minutes, but till now it has not been activated. i feel cheated by vodafone. and i will now do mouth publicity and tell everybody to not to buy vodafone sim card as they dont provide you the services.
