Call them on the phone at 198 (free) or 121 (50p per 3 minutes) from an Airtel landline or mobile.
I did this today. I really felt bad as I love Airtel and it has been perfect for so many years.
What is the highest speed you are getting on torrents? Mine hasn't gone above 3.5 while on Airtel I used to get around 5MBps. Other downloads do touch around 11.5 though.
I mailed them at [email protected] requesting cancellation yesterday. Got couple of calls from Airtel team today with good offers to keep the connection but insisted on cancellation. So, its approved and will get cancelled within 7 days. Their retention team is good and polite and the experience was good. Had 0 issues with Airtel since I got it in September last year. But, Jio being free for now doesnt makes sense to pay 1200 bucks every month to Airtel.
Torrent downloads usually hovers around 3-5 mb/sec with occasional touch ups to 7. On Airtel I used to get consistent 3
mb/sec.
