what happened to getting consumer consent

Im so dissapointed da way ackermans conducts their business. My mom opened an account with them & they decided to share her personal info with hollard insurance & hollard offered my mum a funeral plan that she declined but they went aheard & deducted money frm my mums ackermans acc without her consent. i called the ackermans head office a manager by da name of Mthembeki promised to call back to resolve the issue bt he never did even worse we cant get hold of hollard on da number we got frm an ackermans store.
