HDFC Bank — can't use my account balance

Hi.
My name is hiranmay kanungo. On 1st october 2018, i had 13000 in my account. I paid my credit card bill of 5150. After that my available balance was shown as 2900 and ledger balance was 8000. Is that amount which is showing in ledger balance be withdrawn? How do i recover the extra 5150 which is not there in available balance. Its been 2 days.
