POOR CUSTOMER SERVICE: Capitec is reluctant to provide further information from their back-office system to substantiate that Woolworths received the duplicate payment.

Woolworths has took double payments for purchases, but Capitec is reluctant to provide further information from their back-office system to substantiate that Woolworths received the duplicate payment. Who can I rely on? What has happened to customer service? How can we trust these companies in the future? Why do I have to struggle to get MY MONEY back from these companies? Why are they not taking responsibility for their actions? I moved to Capitec because they apparently low on banking costs, a month later and I have issues like this!!!
