Crying out for help

I am writing this with tears falling down the treatment that African Bank is giving my sick mother is heartbreaking .My mom had a credit card with them when she was still working .Unfortunately she got diagnosed with arthritis in 2019 .She was going in and out of hospitals trying to get better .Her Doctor then decided that she is medically unfit to go to work .All the paper work was done to get her under temp disability at work .we then sent documents to African bank for her insurance to pay for her credit card since she is no longer working .we got a shock of our life when we got told that she took long to calm therefore the insurance can not pay out .WHAT ????????????????????????? She is sick for God sake and her priority at that time was for her to get well and go back to work .She has been receiving call from them ever since ,they even have the guts to tell her that her acc is in arrears and they are handing it over to Lord knows where .She then agreed to give them 100 from that small money she gets from work the very same money that has to pay for her medication and Doctors visits ..The last straw was when they debited 500 from her account last month ...COME ON NEDBANK my mother is no longer working why are you doing this to her ??? Is it because she is black ??? Is it because she is woman and she can not stand up for herself??? Why was she paying for her insurance in the first place ???My mother was sick for Gods sake how was she suppose to think abt insurances at that time ??

I need you to sort this out .I also need to know who authorized the 500 debit check because I know she did not .
