Pathetic banks

My elder mother was a victim of ATM ***** in East London in Greenfields today .She first tried using a capitec atm which was not working then she processed to use an alternative Standard Bank atm in the same area. She inserted the card and the Standard bank atm swallowed the bank card .A white man used the atm and could withdraw money .My mother did not move from the atm as she called the helpline for Standard Bank as she didn't know what to do.she was advised to call Capitec as the account with them .She then contacted Capitec while in the same area was advised that the card is blocked .When she got home 15 minutes later there was a 2 notifications one of R3000 and R1000 withdrawal .Bare in mind this account belongs to my father who is blind that is in need of this money . My mother also suffers from high blood pressure and doesn't need this . I would like an investigation in this and also for my parents to GET THEIR MONEY BACK ..Im very annoyed sies. Why is that our elderly people are subjected to this R4000 is alot of money to loose in a blink of an eye and the banks do nothing to compensate their loyal customers .
