Adene's flowers are dead like her service

I bought a bunch of Adene's flowers on Sunday from a stall in SuperSpar for my mom's birthday. Two days later the flowers are half dead, falling off. I sent a WA as per the website and was only asked if I bought the flowers as a bunch, since then no other feedback, apology or even a replacement. These flowers are expensive and you would think it would last at least 2 weeks, not two days. I tried calling the farm and no answer.
