Defective product

I bought a set of pot from Pick n Pay home ( #***). The pots were bought on the 23 December 2023 and were delivered on the 3rd of January 2024, having promised to deliver 2-5 working days, Pick n Pay home delivered after enquiring and delivered wrong pots. I was willing to keep the wrong pots after having fought to get the pots delivered. I called Pick n Pay home 15/01/24 complainig that there were pot lid *****s that are missing and the pots leak rust from the pot lid when I cook with them. Pick n Pay home informed that they were not going to replace or refund my money because I reported the matter a week late. I am surprised that a company as big as Pick n Pay sell a defective product and hind behind such a statement (seven days late) and not take responsibility, making the consumer suffer because of their supplier. Interesting that on Pick n Pay website it is written that customer's rights are " Your right to fair and honest dealing. Your right to fair, just, and reasonable terms and conditions and Your right to accountability by suppliers" from Consumer Protection Act. Is it fair, just and reasonable term and condition to state that seven days have passed and there's nothing they can do with a product that is defective and a threat to my health? Am I protected as their consumer from their suppliers? Delivery was on the 3rd January 2024 at night and I started to use the pots on the 8th of January 2024. Reported the issue on the 15 January 2024. is that not a reasonable time to report the issue? Be that it was the first time I buy from Pick n Pay Home, I am disappointed and would not recommend it to anyone.
