well if your order was as hard to understand as your post i arent surprised to be honest lol.
I had one problem with the wrong paint being sent, however if you actually ring them they sort it out for you no problems... i think people are afraid of using the phone sometimes. They let me keep the wrong tins of paint and sent me the right tins the next day. Top quality service.
People who know me know the quality of the colour/paintwork produced, which is largely a factor of the paint that I use, and the quality of the spray form the cans.
