Airtel — About account freeze

I am using airtel payment bank account since from many years. The last transaction I got credited with rs 7.5k. Now I want to transfer that money to other account on a urgent basis. While initiating a transaction, im getting error as the debit is disabled due to debit freeze or account is blocked. I think something is going wrong with my account. I don't want to lose the money please help me in solving this problem on urgent basis.
