Incorrect debit order

Good day, Vodacom debitted from my capitec account without my consent and they received a returned debit and i had already queried the matter in the past week and half and to date i have not received feedback.<br> <br> Now they also sent me a statement inclusive of the amount i am refusing to pay since they failed to debit the correct bank being FNB. <br> <br> Should this matter fail to be finalized i will refer same to FSB due to change of banking details without consent.<br> <br> regards
