I ordered 850kg 20mm polar white. 1. The bag is 3/4 full. I spotted right away that it was less than 850kg as I ordered in the past and can twll this was less. Then I check the label and it says 750kg. I discussed this with the delivery guy and he confirmed it does not look full. And that they are usually more in the bag. But he is only deliver guy. Spoke to cutomer service and they replied ''The weight on the label indicates the weight category for our haulier to safely distribute goods onto the lorry''. When asked about complaint department they dont have one. 2. 60% of the stones are less than 20mm with large amount of white sand. I would pay extra and get what I order from somewhere else.
