Would love to suggest that, it is not a right path youre persuing for an amazing destiny. Inspite of journeying with this, I would like to suggest FREECHARGE and in the worst case PAYTM. Few things vex me are:
1.App is very slow.
2.Not all plans will be available.
3.Plans dont match with actual service provider plans.
3.Consumes much time while doing trnsaction.
4.Most of the times, transaction gets flunked though there is called so plan.
