National Payments Corporation of India [NPCI] — not getting lpg subsidy from my sbi account

Address:

Pune, Maharashtra, 411044

I have linked aadhar card to my sbi bank account, still when i check my lpg branch they said from ncpi the aadhar card is still not linked.
I call bank again they tell check lpg, all in a cycle. No one knows the system where to check?
Even after i link and delink aadhar to my bank account sbi, they show in lpg gas as linked but in lpg application, they cannot see subsidy in account, only after ncpi site shows linked we get subsidy. The lpg people said we need to link and delink and after 4-5 times we will get subsidy.
Why i cannot get my subsidy?
