Reef Critters selling sick fish

In 2023 i have purchased designer clown fish form Reef Critter in Johannesburg South. I few days later they started to die and i have lost most of them. On inspection i have found the fish to be sick. Reef Critters did not show really interest in helping, only sharing advice. They played the card that there was no refund nor compensation on life stock. Almost after a year i went back to look at the fish again. I was told their fish are in good condition and no need to worry. I purchased 2 fish from them again abd added to my display tank with other fish that has been up and running successful for a few months without any losses. A few days later i noticed the one fish i have just purchased from Reef Critters was sick again. Long story short within a fee days i have lost all my fish i had in my tank. When i made contact Reef Critter just said they will not take liability becaise its life stock. They also **** about they doing their best to make sure fish is in good conditions. They got the fish in the Thrursady and sold them by Saturday already. They try to sell fast so the risk is on the customer and not them. For the record these fish are very expensive and i have thousands of Rands losses now.
