****** money

First National Bank has gone from the most trusted bank to being ***** and ********** now. On two separate occasions my mother who is over 60 has money ****** from her bank account. The first time it was R5000 and now over the weekend it was R7000, she went to the bank as per usual to report this. The response that she was given is that money is gone yes but they can't trace where it where it went or what happened to it, and a ***** case has been opened whereas the very same line was used by them when she lost the first 5k few months back. It's very ironic how this happens just few days after she had gone to the bank to go change the password for her banking app, because for some dodge reason her finger print authentication was not valid, this is also a frequent thing. And they change the password for her all the time, so they have access to her account. Someone help me on how I can sue FNB bank Graaff-Reinet branch, enough is enough she is one of many.
