Disappointed in service from Fair Cape Dairies

Good say, I'm in need of assistance. So on 30 March 2020 i purchased 3x 6packs Fair Cape Dairies milk at my local wholesale outlet. When i opened the one box the next day, it was off despite the expiration date to be in October. I then called their customer service line and was assisted by a guy called Midian, who went on about how well he knew my area, after all the "small talk" i provided him woth all my contact details and the info from the box to identify the batch. He promised that it would take about 3days for the milk to be replaced due to the lockdown and him not being sure how much call outs the drivers would have. It is 11 May and i called them on 31 March. To date i have not had any feedback and/or apology from Fair Cape Dairies. I ended up having to spend more money to go buy more milk. This, as a paying customer, i feel is unfair especially considering the promise made on the 31st of March. If i was told that i would not be reimbursed my milk, i would have just left it, but i was promised my 3x 6packs milk back. What am I to do now, im still sitting with all the milk, coz i told the guy i only opened one box, and i was under the impression that they would take it back amd provide me with fresh milk. I really just need my milk reimbursed. Pls help. Nazley ***
