Should I use recharge apps or provider's website?

You are free to do the online mobile recharge using the provider’s app or website, since both are convenient. However, you may get cashback offers and discounts if you do the online mobile recharge using the myAirtel app. I used to use third party recharge sites earlier, but the recharge would sometimes not get through and my money would also not get refunded! Using the provider’s recharge tools is better.
