Airtel — internet not working after recharge

Address:

Saharanpur, Uttar Pradesh, 247001

I made a recharge of 345 rupees pack on 24th september from the airtel app. I'm supposed to get unlimited calling and 1gb/day internet as per the plan details. The internet worked fine for few days but then since last 4 days i can't access internet on my phone and it shows zero mb data remaining when i checked my account. I've been facing a lot of issues since i was travelling for the last 4 days so kindly resolve this issue for me. I lost 4 days worth of data due to this error.
