Paid for items but got cancelled due to apparent no stock.

I ordered and paid for 30 products from takealot on Friday, 15 may 2020. I received an email stating that order was cancelled due to no stock. A few hours later I see the exact same items at a different price stating that there is stock.

I saw these items at a certain price and paid for it. They changed the price obviously higher and are now stating no stock but there is. Today I went online 7 of my items are showing stock and I am able to even add them to my cart.

They are offering me credit which I don't want. I need my items. I paid for them. The stock was on hand when I bought them.
