Airtel Payment Bank add money issues

I added 3k to Airtel Payment bank to be used for an offer running in milkbasket. It’s been nearly 24 hrs and it’s still not added.

Then called customer care and they are cooly saying to wait for 5 business days and it will get added or reversed to source account.

That’s very cruel in today’s modern banking, don’t you think? 5 days to add money it seems! Payment was done via UPI, amount was taken instantly and even got a screen showing transaction success with transaction ID also. Still they want 5 business days to credit it seems

Anyone else faced these kind of issues?
