CAPITEC BANK REFUSING TO REFUND UNAUTHORIZED TRANSACTIONS ON MY SAVINGS

I have a savings account with Capitec bank where I had saved up to R6900 and on 30 July 2019 I discovered that all my savings on that account were gone. I then logged a query with Capitec bank and was given reference number ***1 by Freddy Tshaba who then said I would be assisted within 8 working days. Only after 8 working days a lady by the name Galaletsang called me to say unfortunately they cannot assist me, which baffles me because she mentioned that bulk of that money (R5900) was transferred to other Capitec clients' accounts and R1000 was sent to Shoprite, which I clearly did not authorize. It's strange that they cannot assist when there is in fact a clear trail of where that money went, which they can rectify by just debiting those accounts and crediting mine for me to get my funds back. Further more, when someone fetches money from Shoprite, they would have to produce identification of some sort and therefore it's clear that Capitec is unwilling to assist deliberately or someone in the inside is assisting with the ***** committed against me. I would appreciated if I could be refunded my R6900 back!
