After hours of research I finally decided on this deep navy colour for the feature in my new flat. When I opened the tin, I saw the colour wasn't navy but purple. But the inner rim of the lid shows some navy colour, and I double checked the tin. The information on the tin matched my order details. So, I believed the paint will change colour when it drys. But it hasn't, it stays purple as it is. I contacted the customer service straight away. Because the new brush & roller cannot be re-used again, and I needed to purchase white paint to cover the purple. I would expect Graham Brown to compensate for this. However, the customer service team don't seem to care about my loss, only can offer replacement or refund. And argued that I shouldn't have painted the whole wall when the colour didn't look right. I really don't know what her point is? if I didn't paint the whole wall, the roller & brush were still wasted. and I will still buy white paint to cover the purple. And I did check the information on the tin to confirm that I received the correct paint. To me, this company does not care about their customers. Very disappointed!
