Airtel — plan not activated for 399/84 days validity

Address:

400066

I had received call from airtel representative for offer of ₹399 with 84 days validity unlimited call and 1gb /day internet. I still cannot see the offer on my number yet. Is your services only for namesake??
I was told it will get reflected in 4 hrs but still it's not displaying... Should i keep waiting.. My recharge is zero and i don't have data or balance to make call
