Airtel — Did not receive Amazon prime membership which is included in the pack

I did not receive Amazon prime membership which is included in the 699rs Airtel plan.
I cannot contact Airtel customer service, on their app the chat bot says issue not related and when i contact the customer service phone number, it's an automated bot call which is useless doesn't help in any way
And i even contacted Amazon customer service, they told me to get entitlement ID from Airtel but how can I get it when Airtel doesn't let me ask such thing in their customer service.
