********ly debitting my account

the Inqubeko yezibusiso company have been debiting my account for R99 over serval months without my consent - the sometimes debit twice a month on random dates. i only noticed today and checked my statement and debits go as far back as February 2015. any amount less than R100 wont prompt sms notification so ive never notice as i have 3 accounts with Capitec. they debited 15&2 October, 4&25 September
