False advertisment

I am very disappoint with you guys,,just ordered online small triple decker the one with enegade for R79.99 at Kuyasa Mdantsane this afternoon. On my arrival for collection they told me they do not have enegade drink and they do not replace it? How is that possible? They not supposed to give me another drink that cost the same?

How can you guys advertise something that you do not have??
