Sub-standard service from Woolworths.

Received the worst service from Ross or whatever his name is from Woolworths Financial Services - credit card department(Call centre). My complaint is about a WRewards quarterly voucher that was sent on the 11th of December 2024 at 17:42, however, i was t9old that the voucher was redeemed on the 6th of December 2024. Anyone with half a brain would realise that i wouldn't have redeemed the voucher, but the agent told me that there's nothing they can do. Woolworths is slowly becoming like Shoprite.
