Airtel has charged me Rsprotected.protected/- for August-protected bill amount, which is not legitimate. They have enabled international roaming & data service without my consent and charging me heavy charge for Data usage. I am employee of VISA credit card company, Mahadevpura, Bangalore; company has sent me USA for project assignment from May-protected. Last month I have travelled India from 5-Jul-protected to 6-Aug-protected. While travelling to USA on 7-Aug-protected my mobile data was on. On the way to USA I have received text message from Airtel that “International roaming” is not active on my phone. So I did not bother to turn mobile data off. But on protected-Aug-protected Aug I checked one of text message from Airtel about data usage alert mentioning data of Rsprotected/ is used and asked me to text back NO to stop service. I have texted back saying NO. After final bill I checked total amount billed was Rsprotected which was shocking for me. First of all they should not enable data service or international roaming without my consent. Please Advice. I wish that my consumer complaint will get resolved soon.
