Let down

On the afternoon of the 27th Dec, I placed a Click & Collect order for Braai Lamb Tails for the following day at Sunward Park Foodstore between 2pm - 3pm. Order was successfully placed, huge surprise when I got to the store and found that the order is not ready ...worse no-one knew of the order. I was told that it was somehow missed and actually there was no stock in the store so they will call me, my details were taken. Luckily I was ordering for the braai on the 1st so there was still time. On Monday the 30th I received a call and was informed that actually the stock is not even available from Supplier, even. I made it clear that I need Lamb as I have the braai menu sorted. On Tuesday the 31st , I was told there is nothing that can be done for me and its Click & Collect dept. Only on this day do I receive an email cancelling my order and also saying that my refund will only be available in 21 working days (I used my Capitec card). This meant I had to either use other money and buy lamb or not have lamb at the braai. I am a huge customer of Woolworths Food (buy my fruits and veggies weekly there + meat), this is not an experience that has to be linked with Woolworths brand. Why should I wait 21days for a refund? I placed an order and it was successful, why am I being punished? Why couldn't the team make a plan and source from any other stores outside Boksburg? Even today when I checked on the App the Braai Lamb tails are still available to be purchased. Why did it take so many days for the order to officially cancelled?
