Airtel — airtel payment bank no debit allowed on this account

Recently deposited an amount of rs 2000 in my airtel wallet. Now when i try to do any transactions from it a notice appears and says "debit for this account is not allowed".
Cc from airtel what does it mean. Quite frankly i care less about what it means. I want you people to kindly solve my problem because i got other things to do too
