Angry customer

A month back there was a sale for brutal fruits ruby something you buy 12 pack for 100 rand, their sale started till it end there was no stock of which this is not the first incident. We did a rain check with them last week i was told that stock will be available on Tuesday. On Tuesday still the was no stock we went on Monday still there was no stock instead there was another sale for Brutal fruit 500 ml. We spoke to Thabiso the supervisor that how is that a huge store like checkers hardly has stock available i must say im very angry cause we i personally feel that i never get to benefit from the sales they make.
