Makro online

I was placing an order online and I saw a voucher /coupon for MAK500 for all orders above R5000 which is only applicable on 13/12/2023. Added an item that is R5 499 & added coupon code, my new total is now R4 999. When I go to add payment method total changes back to R5 499.

Tried contacting them on call, first person I spoke to said I must be quick when doing the purchase as it times up (timed up/ timing up). The second time I called the lady said the Voucher is only applicable in store. The chatbox got disconnected and I couldn't connect back.
