Macro false advertising

On 19.01.2024 I bought a hisense 32l airfreyer from Macro online.The add said ' mote for lessBuy a Hisense 32l airfreyer plus a 5.2l airfreyer for R2499. Saving R1500'. Macro only delivered the 32l airfreyer. I phoned the customer service department and was informed that I cannot get the offer because my airfreyer comes from a 3red party vendor. I asked him to check and the add does not say only instore he then put the phone down while I was still speaking to him.I phoned again and another call center operator assisted me and said she will log a call. This is false advertising, I would not have bought the airfreyer if not for the promotion
