Dulux Acrylic PVA - Worst quality paint on the market

Bought Dulux Acrylic PVA, tinted to Dusted Moss 2. Painted the entire home as per the tech sheet and so excited to see the finished product the next day only to find my walls full of streaks. Some of the walls have up to 4 coats on them in an attempt to rid the walls of the streaks but nope, streaks remain. Walls were is great condition and painted with Dulux Trade last year. We wanted a change in colour and now I cant move furniture in as I cant leave the walls like this. The amount of money spent on paint, hardware and labour saddens me and thinking about the time its going to take for Dulux to respond, review, have a look, discuss, deliberate and provide feedback will most probably leave us living in a home with terrible walls and no furniture.
