Refund not showing

I have been waiting 9 days now for a refund to reflect back on my Capitec Card. Capitec says Woolworths need to stop pending but I have mailed Woolworths 4 times already and they say the problem is not theirs but gives minimal help on how to resolve the issue. This is MY MONEY. How can a business like Woolworths keep peoples money when they return an item? This is ********. Please revert. My Capitec app says the money is due to me but is pending.
