Airtel — Airtel Free Amazon prime membership

Address:

pune

I recharged my airtel number it included free amazon prime membership but it is not activating. I called so many times to airtel customer care but they didn't solved my problem. Every time they say to activate it through Airtel Thanks Application. I tried through their app but it is not activating and when I asked them to provide me entitlement ID of Prime membership, they say that they will share through SMS but after disconnecting the call, they send blank or false message only. I am frustrated by calling customer care so many times.
