My elderly grandmother, who has a hearing impairment and uses a simple phone, accidentally made a long-distance call while her phone was unlocked during the night. We didn’t have any security measures like a PIN or fingerprint lock, and she doesn’t understand how the call happened. Now, Aircel in Chennai is demanding a huge bill, over ₹10,000, even though her credit limit is only ₹2,000. Is this fair?

It is unlikely that the bill is fair. Under Indian law, telecom companies are obligated to provide reasonable and transparent billing practices. Since your grandmother’s hearing impairment and lack of phone knowledge make it difficult for her to understand and control phone usage, Aircel may have to justify the exorbitant charge. You should contact them and explain the situation, and if the bill remains unreasonable, consider filing a complaint with the Telecom Regulatory Authority of India (TRAI).
