Rotten, stale and bread mould on the Sunbake rolls

On the 25th of August my wife bought a pack of Sunbake rolls at Usave GA-Rankuwa Zone 6 only to find that it's having it's best before date as the 26th August, on arriving home same day we found them rotten and stale having bread mould. This is evident that they don't rotate their foods on the shelves timeously, I tried in more than 2 occasions to talk to RCL foods as the owner of Sunbake products but got no help. I'm wondering whether this Usave GA-Rankuwa Zone 6 feed their Customers with rotten foods. And I also want my money back. I'd rather do my business with other stores.
