Spar Kasselslvei Bellville i disappoint us, BIG TIME!

On Sunday 29/08/2021 I bought giabata rolls at Spar Kasselsvlei, 4 of them. The time was just after 1 but before 2 o clock. My husband cut it open on Sunday evening, guess what, nothing inside, just a crust. How does one bake stuff like this? The middle part is what you eat to fill your tummy but there was nothing. It was too late to take it back as it was at about 8 o clock. I took pictures which I have on my phone is you need to see. We never ate it and put it back in the packet. I was looking for the slip but could not find it as our son already emptied the dirt out in the big bin. And with covid i dare not scratch int he bin. This is very disappointing, a shop as big and expensive as Spar??? We shop at Spar almost every week if not two or 3 times a week. Kindly advise what can be done in a situation like this as we have the rolls at home, nothing to eat. How bad is that for business. The top part of the roll was as white as snow, why? Can anyone explain that to me? I bought a few items and went back to buy more items as I forgot something. And that slip I have if you want to see the time I was there. I am aware that one cannot see inside the roll if it bakes but something must have gone wrong. Your urgent and prompt response to this message will be highly appreciated as the rolls are not edible.
