Notes at the shelf misleading and ambiguous

I did shopping at Makro, Alberton on 16/11/2022. I had an encounter, which I find as a regular customer, unsatisfactory. The two notes at the Coffee shelf indicate that the “Jacobs Kronung and Gold Coffee, any two for R215,00 “ I wanted to buy two, Decaf, containers. At the till I was informed that Decaf is excluded from this offer. The Supervisor wanted to show me the brochure as advertised. This brochure was not displayed in the store at the shelf. I find these notes at the shelf misleading and ambiguous. It does not anywhere, on any display at the shelf states the Decaf as being excluded. The supervisor, to me as a customer, was not helpful at all and at one point I felt the she was taunting me. I warned her not to do so. I request Makro to respond please
