Airtel — recharge not reflecting in my phone

This is about my mother's prepaid no. I had got 3 recharges done: for 100 rupees on on july 28, and for 10 and 100 rupees on july 30, 2018 respectively. The sms after the first recharge said 'recharge failed'. After the second recharge that i made with a different debit card for 10 rupee, the sms said 'successful'. So i put another 100. Today is aug 2. Voice message on her phone again is 'your pack has expired. Please recharge...'. The recharge was done online. Please resolve the issue soonest because my mother is not able to make calls. And i would like to know where the recharge amount has simply vanished.
