Capitec owing me money

Money went off my account that declined on the merchant's side and its been a whole month already where capitec still haven't reversed my money back into my account. And they dont even have the decency to follow up with me when they keep saying they will. Eventually when they do call me they keep stretching it out and it just keeps getting said that it will be reversed on the next occation. This is disgusting service and very disappointing because its like they dont care that they owe me money.
