Redeemed Voucher

Unilever's services is shocking!!! I received a free ladies' roll on from MR P and entered the competition for you to win a prize, and I won an R100 Takealot Voucher, I wanted to utilize the voucher and it tells me the voucher has already been used!! Unilever was contacted and notified on the 19th of October 2022 about the matter, and I was informed that it would take up to 7 working days for feedback. I have subsequently followed up 3 times, with today being the 3rd, only to receive the same feedback every time which is: "Kindly be advised that the agent working on your query has escalated the matter to the relevant team for feedback however, they are still waiting for feedback." Come on, I know this is a small matter - but it's the principle behind it with a promo advertised! Makes me wonder about the vouchers given!
