standard bank useless

I have had thousands of rands of ********** transactions done on credit card this i only became aware of once the last transaction did not go through, my notifications as well as statement had been turned off on the banks side, this became apparent after speaking to Jesse at ***** and Jeanette at the bank, this was on the 7th of August2018. I was then asked to mark on my statements which they had to send to me cause i never got them which transactions were **********, this i did and sent the statements through to the ***** department which they somehow never received but i have automated responses from then that it was received. Then on Fri 10th i got a mail saying they cant do anything until i complete a dispute form, this i submitted on Mon 13th to Kenneth at cashbacks plus the statements for the 3rd time and had no feedback from him, i then spoke to Genaveve and Lerto at which i presume is the ***** department as mails have no department or contact numbers on and they asked for the documents again which i sent through then they mailed me to say its at chargebacks which is a different department, yesterday i get a sms from the ***** department to ask if i want them to look into it (how pathetic who is not doing their job) i soke to Morano who then asked if i want to speak to her supivisor who is standing with her which i agreed to she put me on hold for 7 mins with no ans from supervisor can somebody pls help, regards Ken ********** 302
