No Ammonia Creme Hair Colour (70g)

I ordered two packs and received today on 23rd of December, 2022 without developers whereas it is clearly mentioned on the pack cartridge that it is to be used in 1:1 ratio. Where shall I get the developer if the pack comes without it.. This is just another way of cheating customers... Want to return the products.. please inform about the return policy...
Feeling cheated...

This color comes with only hair color tube. No developer was provided with this. I have never seen or used color without developer. I didn't knew at the time of ordering. I would say, it is quite expensive if you have to buy developer seperately. Cannot say about color quality yet as I haven't used because of this developer issue
