Airtel — wow the best network in "not helping customer in right way"

Address:

Chennai, Tamil Nadu, 600032

I accept that airtel is the best provider among all and including customer support also... They are doing good and following up : (

But it's a waste of our time...

I am following them more than 30 days.. And didn't get any positive solution for me now...

The mail i sent to airtel cc ":

Dear airtel

I purchased my samsung s9+ on airtel store and the date of delivery is 10-apr-2018 and i was using the mobile about 20 days only... Suddenly i saw one straight line on my screen and i called airtel customer care and asked for the mobile replacement since it's 20 days old only. They advised me to apply for airtel secure service and applied more than 4 times after that i raised a complaint with airtel customer care... And definitely, i loved their support they followed me back on the phone... After few hours i got the call from"one assist"on may 6 and they said please upload the clear images of phone.. I said ok (Screenshot attached) and reuploaded all the images immediately and i didn't receive any calls from them afterward and re-checked the airtel app on next day and again it's asked for"proceed to checkout (Link new apply)" and i left it because got tired of complaining this to your customer care (You can check my log details from your side). After that, i got an accident on may 10 and my phone has broken a little bit!

What can i do now?

It's just 20 days from purchasing date i saw some line on my mobile and asked for the replacement and you people didn't help me out

It's a rs.65, 000 product. How can i pay without using the product.?

Please think it from my perspective! And do the needful

Until i won't pay the emi and i know it will affect my credit history...
Without your reply am not gonna pay...

Do the needful as earliest...

Attaching all the images taken before screen broken (You can see the line on before images)

Attached one video now after the met accident and broken screen and it should be resolved before that...

1. Phone replacement didn't happen
2. I applied for airtel secure service after many attempts it didn't happen
3. Made a complaint about this in airtel cc... You can check my records
(And today also, made one complaint)
