Expired food & managers who are rude

I purchased Provitas on the 14 August 2023. I ate 2 individually packed packets on the 15th & 16th until I started becoming sick. I looked at the package and saw that it had already expired on 14 January 2023. I went to Dis-Chem to report this incident in my sick state and i was told that they have to follow procedure to lodge an incident. I do not understand how does Dis-Chem make a client who is sick and need medical attention to wait until they have done their processes. I mean what is there to investigate if I have the receipts and I am telling them that the expired item made me feel.

The manager did not care about my health but was concerned about the process they need to follow. I am on chronic medication and they did not even care to ask or be concerned how will the expired item affect me.

The guy (Roland) further was proud that the expired item happened before he could work for the Potchefstroom branch, however he is currently the manager there. He could not tell me how long will the process take.

I filled in the form and signed it then when I left he added more info to the forms which was not there when i signed the form. This is disrespect because i am black. I will definitely escalate the matter to my lawyers.
