On 26 May 2015 there was a ********** activity of R 2 899,40 on my post-bank account where I was asked by the Post-bank customer service to report the matter to the police station and to take all supporting documents to any post office,On May 28th I took all relevant documents with my case number to Silverton Post office where I was assisted by Mrs T..E Nkabinde.She requested all the documentations,i further gave her the fax number *** where she was to sent the documents to Maryna Rossouw in the Post-bank ***** division,She agreed to do that and after some moment she come back that she has sent all the documents.On 04 June 2015 I made follow-up with Post-bank and the agent told me that forensic will contact me within 10 working days.On 09 June 2015 I made follow-up again and was informed that there is no trace of my documents.I then went back to Silverton post office to make enquiries ,Mrs Nkabinde told me that she has initially sent the documents to forensic,However when I phone forensic they denied receiving any sorts of documentations except the e-mail that come from Silverton to activate my account.I have personally e-mail my documents but not prepared to wait further
