Hey Esma,
I'm so sorry to hear that this was your experience with the detergent.
Our testing has found it to be one of the most effective detergents on the market, so we're very interested to know more about why/what it didn't work on.
The effectiveness of the detergent can also vary depending on a few factors like the dosage used, the size of the load etc so it's tricky to troubleshoot for you what went wrong without more information.
But if you'd like to get in contact with us to share more detailed feedback, please feel free to do so here: https://thedirtcompany.com.au/pages/contact-us
We also have a 30 day satisfaction guarantee and I can see that you're only just out of the 30 day cut off, so I'm more than happy to still honour it and process a refund back to you for the product, just let me know via email.
Thanks so much,
Zoe
