ROTTING EGGS/DEAD ANIMAL PAINT / BUILDERS TYGERBERG

Builders TygerBerg. On the 1st of april 2018 we bought lots of paint and hardware and spent A LOT of money from Builders. A particular white paint FIRED EARTH we bought STINKS. The paint smells like cat's urine or rotting animals. it was only used in my daughters room. The smell, emitting from the walls painted with the Fired Earth is gets worse and worse - 2 months later it still STINKS . I have tired EVERYTHING to get rid of the smell. Fired Earth Representative and Builders say that it does not smell and have had it tested !! Obviously they will not accept responsibility. I dont want my money back - i want them to repaint/fix the wall !! to date no response!!!
