ABSA Doesn’t do enough to protect their clients information

Over the last few months an unknown suspect has been hacking my e mail and adjusting my company invoices. They remove my account number and place theirs and hope for the best. The account that is being edited on my invoices is as follows ABSA Account, ***, belonging to a Lerato Moketsi. My concern is how does ABSA not have control over this situation because when we apply for credit facilities we need to submitted tons of paperwork, sign a million times all over and be inconvenienced and yet all our money is entrusted with them. Suspects get ahead at ABSA at our expense and have little to no verification at all or is this a ABSA bank **** to give ********** access to our hard earned funds
