Dulux pathetic service and paint quality

I bought dulux acrylic pva paint it was tinted to crimson, I was told it was a a very good paint and believing in the brand I decided to purchase it from our local hardware store. Upon purchaseing I equried of the paint will catch on my wall I previously had dulux white paint on it and my walls are fairly new and clean. I bought a 5l for two small rooms and to my surprise it did not even catch on the walls we put on two coats of the paint and still it didn't I had to put on a 3rd coat for it to actually catch. The remaining of the paint I used one coat in the other room however it's pathetic paint quality did not even cover neatly. This is actually not the reason I'm so ****ed off. I went back to the hardware store were they called up the dulux rep my husband spoke to her and she ensured us somone will come and inspect the walls as she believes there's something on the wall it's been a month nobody has come to our home. Our walls in one room are patched up and looks terrible. If the paint quality is bad the customer service is worst. Firstly dulux is not a cheap paint it's quite expensive and their service is ****, there's absolutely nothing on our walls as it's a new building and it's quite clean. I've been eeb other reviews about dulux and all is bad. Please stop false advertising the quality of the paint and service yourl provide because it's of very low standards. I will never ever recommend dulux to anyone you wasting your time and money. Atleast if their service was good there would've been hope for them but unfortunately it's as bad as their paint....
