Stinky,
call me stubborn but I would be hounding them for a refund for the broken pavers. I've never let anyone get away with that sort of stunt - ever. I find that giving them all the reasons and the steps you will take(lenghts you will go to) usually gets results in a few days. I once told a phone supplier that I would wheel my wheelchair-bound wife out the front of their shop and hold a press conference as they would not honour their extended warranty on the phone that she needed to be able to contact me on 24/7:mad: . They contacted me the next day and told me that they would be repairing it under warranty after all;)
