Health/well-being products distributor doesn't seem to care about my health and well-being

I ordered an expensive pre/probiotic from them on 4 January with a request to deliver on 24 January. On 24 January I reached out on their WhatsApp line to find out where the delivery was, and was advised the order would be shipped on the 25th. It arrived the afternoon of 29 January, 6 days late. Except for the incredibly apologetic person at the end of the WhatsApp line who tried to rectify the situation by calling me to apologise, there was zero proactivity from this company (they could have offered for me to pick up the product on the 25th knowing as they did that the courier company would not deliver on the weekend, offered me a credit for the delivery, offered me a discount on my next purchase; the manager could have called to tell me they'll do better next time...so many opportunities to put this right simply left on the table). I explained without going into detail the impact on my health of not taking a daily dose of this product for 6 days, and while the woman was sympathetic, this distributor of health & well-being products really seems to have zero care for my health & well-being. I asked the woman to get her manager to call me, and I asked for a credit on the delivery. They were happy to take my payment in early January, but for some reason were incapable of arranging the delivery for the requested date (requested on the order and over the WhatsApp line to confirm). They compounded the error by using a courier which was slack about delivery schedules (the commitment was for delivery within 2 days, and the courier acknowledged that they were overdue but also provided no explanation or even an apology). I am now trying to find out if there's another, more reliable and caring distributor of this product, which has been transformative for me.
