Vodacom & Flook ****/*****

I purchased a Bondiblu glasses voucher on the Vodacom App with 1200 of my vodabucks. I received the SMS voucher 3 hours later. I than immediately attempted to redeem this voucher on the Flook website. There was a list of sunglasses that had no 'SOLD OUT" sign on but when attempting to add any of them to my cart it stated it was out of stock. This is a complete hoax and **** between Flook and Vodacom. The voucher is only available till the 05/03/2020. Vodacom has not given me back my Vodabucks
