Account Frozen

On the 28/04/2016 Nokuthula Jumba has transferred R3637 which is the money she owed me, and on the 03/05/2016 morning when i checked my bank balance i realized my money R2375.19 was not in my account, i then called Capitec bank to check with them where my money disappeared to, the consultant i spoke with who did not even know what was after spending my airtime and time for over 15 to 30minutes . She finally told me my money has been frozen due to that Nokuthula called the bank and asked the money to be reversed to her account she **** and said she made an error with the reff no when she was doing a transfer. I waited for the call from Capitec and this morning 04/05/2016 i got a call from Capitec advising of the wrong transaction in my account...i advised the lady that payment was made to the correct account and advised her that Nokuthula is trying to do ***** in my account, when i asked the lady when my money will be unfrozen she told me the funds will remain frozen she doesn't know until when...this is my account, i need to use the money frozen in my account, my landlord is waiting for rent to be paid Capitec cannot control my account because someone is trying to ***** my account...i need my money to be unfrozen by the end of business day!!!!!
