I would like to share a link today with everyone which will show you how airtel treats it's so called valuable customers.
And what surprises me more is that these people are from higher authority. I won't explain much about my experience, rather share a link to a video in which I am in a conversation with an employee from airtel services. Then I am sure you will port your number to some other telecom service immediately if you are an airtel user currently.
