Plascon micatex sprintide colour is white and not the same as indicated on colour chart

We purchased 6 20 litre plascon micatex sprintide from builders warehouse strubensvalley. I am extremely upset. The colour is certainly not the colour I chose. The sprintide has come out pure white rather than the colour indicated on the colour chart. I wanted a low maintenance colour and now have pure white walls. I want to be reimbursed for my purchase of the paint and the labour. Really ****ed off!!!!
