Airtel 4G, you get 2G service if you are lucky. Most of the time 2G doesn’t even work. Customer service charges for technical service to make a complaint. I am not sure how they are getting away with such poor service.
Calling Customer Service won’t help anyway. You get the message your problem is resolved.
And there is no way to get money back even you don’t get a single minute of service. If you hear there adds you will be blown away. What a scam.
