I had apply for Balance transfer and Top-Up loan to ICICI Bank . They said me regarding two separate cheques will be release at time after loan sanctioned.on 31th Dec 2015 they make two cheques ;so on that date interest start for me.But they release only BT cheque only ;said me Top up loan cheque will be release after all produce complete regarding previous loan closure . I had submit all documents related to Loan closure on 21th Jan 2016; but still not release Top-up cheque.
