Withholding Funds that do not belong to them !!

During the course of last week , i had received a large deposit in my nedbank account which i was made to believe that it is still active , i had borrowed this money to settle suppliers as i am leaving Wednesday 23/12/2015 out of country , only to discover upon receiving the funds Nedbank had frozen my account , so i went over to Argyle Road Branch (Durban) whereby i had to make 4 trips !! due to responsible clerks not giving me proper information that was required , eventually all documents were submitted on Friday , only to be told on 21/12/2015 , that i would receive feedback on the Thursday (24/12/2015), if they can release my money !! If my account is not worthy just dont receive my funds , not receive and then hold myself ransom, my suppliers furious and so am i , my own money is held against my will - PLEASE SOMEONE HELP
