You can't argue with the explanation given by Marshalls - it's pretty much what I would have said had they not beaten me to it, and they key fact is that variation in hue does not affect the performance of the blocks, nor their service life. It's purely aesthetic.
It could be argued that, had the blocks been more thoroughly randomised prior to laying, the variation might have been less noticeable....might have been!
However, what you are left with is an aesthetic issue and as such it's wholly subjective. What you see as unacceptable, other customers might not even notice. Now, had this been a high value, premium product sold on its visual attractiveness and aesthetic appeal, Marshalls might have judged that it wasn't quite as lovely as they'd like it to be, and offer you a swap, but what we are talking about here is cheap-as-chips concrete block paving, on which they are lucky to break even, if truth be told, and it's a product sold more on its function and 'value-for-money' than aesthetic appeal, so you can't really expect more than what you've had....and explanation, and a totally valid explanation at that!
Of course, if it bugs you that much, you can buy replacement blocks and swap them out, but, in a year or two, what you now see as variation will be practically undetectable. As the concrete continues to cure, and the dyes "mellow" with exposure to UV light, those variations will dissipate and all will begin to look pretty much uniform.
If you wanted strong, stable and vibrant colours, then CBPs were probably not the best choice.
