Colour variance in wall tiles

I have just been renovating my bathroom and bought tiles from CTM. I now have a wall with three different shades of what was supposed to be the exact same tile and it looks horrible. Have contacted the customer service for advice and asked for a consultant to come and take a look but no response so far. I hope to hear something soon. Any other individuals out there thinking about tiling - you may have to check each individual tile, as CTM seems not to be able to guarantee delivering the same tiles between boxes. Prepare yourself for a colourful wall even if you did not want one.
