Right now i am in saudi arabia, whenever i am recharging my prepaid number automatically deducting amount then balance become zero. This was done without my permission and reduced my balance to zero, causing considerable inconvenience. Yesterday i recharged rs.130/- through net banking (02.01.2018), but now the balance is rs.1/-. I thought to keep balance on my number before entering to my home country, but airtel not allowing to keep any balance in my account.

Please refund the money and i request in the strongest terms to not do this again. I request you to tell me how to prevent this from happening. This is unacceptable,

Regards,
Reshmi
