PLascon Paint Sucks

I have been a supported of Plascon paint for my entire life, I run a small business called Billy The Builder, and use about 60 liters of paint per week. So I bought a 20 liter drum of Viva white acrylic paint from Build IT Brakpan and my staff had used the paint a couple of time and complained about the quality....I dint think too much of it...but I then used the paint last week, to give a final coat to a newly installed ceiling that had been primed and had already been painted twice with this paint. I honestly cannot tell you how disappointed I was with this paint....I climbed off the ladder and stirred it thoroughly again but it is like white water..it has consistency but there is absolutely no coverage. I contacted Plascon and they gave me a million questions about the clients address, phone number, what was the surface...was it interior or outside. I answered all their questions to no avail. Here is the deal....I do not want my money back...want I want to know is, if this is Plascon's new quality.....I will find another paint manufacturer.
