Refund

I'm a Capitec client and I'm Soo disappointed with them, i bought some item's at pick n pay ASAP and Woolworths online and some of the item's where sold out, Capitec took the full amount on my banking app and they didn't refund my money for the sold out items. I spoke to some agents and they told me it's not capitecs fault I must call pick n pay when I call pick n pay the say it's capitec. I'm going back and forth between the two companies and no one is willing to assist. Capitec is robbing their client's. I'm not happy with Capitec Bank.
