MEDAL PAINT SAND OLIVE POOR QUALITY PAINT

We bought 20l Medal paint Sand Olive colour I must say this is the worst paid I have ever bought. Upon usage we mixed the paint well enough but I realized as my painter was painting and over time the edges where darkened and the paint is not blending together. Then I had to buy another 20l same paid and the results where the same . I wrote my review on their Facebook page and the contacted me for I provided the the batch number from the two buckets . they responded from sampling the paint on paper that my complaint is invalid from spending lots of money and getting poor quality work from their paint.
