Account frozen without notice

ood day my name is lyncoleen leshabane I'd no,on the 15th I received money of R800 as expected from Mr mashaba.the money was received in my account successfully.I used it as I was supposed to ,later that day I missed a call from the bank in tzaneen I called back the bank I was told by one of the consultant that my account has been frozen as there was an unauthorized payment as per the complainant. Since then my acc has been frozen I have not received any notifications from the bank about what is going on,what is the processs to follow and more expertialy what is going on. I have visited the bank today no one is able to assist the. Consultant who assisted me called forensic department they are telling me that I have to call the complainant to ask them to bring in an affidavit. Where does the bank place me must I beg someone t bring in an affidavit ,I a person make a bank transaction and then decides otherwise about it after doing it how is that my fault? I feel that my situation as client is not considered as there has not Been any formal communication from the bank.the complainant seems to have said the transaction was an unauthorized payment 'in the process of this I want to know my account has Been frozen but In the process what is the bank .no one can give me any information......an unauthorized transaction states that it is a ********** act it means the money was not legitimately sent.I have uncovered that there is a possibility that there is possibility Patrick mashaba used his fathers money to pay back money on my account .....I am saying that is a possibility ...........is it not the clients responsibility to keep to make sure that they keep their pins private and confidential.I feel that I am not treated like a Client I am not communicated to I want to know what is the process in this what options do u have as a Client as well and if my account is been investigated why was I not informed.I want a reference number for this case, I would like an updated .I am pleading that a finding be found as soon as possible because someone's negligence has placed me without access to my account.I have visited a branch they called forensic that department was no even willing to help.I am not happy.Please advise ...... Hoping for a positive feedback as soon as possible. Thank you
