I ordered sand, and the boards were brought to the roof for the first time, a couple of already cracked ones, I turned a blind eye to it, then I ordered sand and crushed stone again, I waited for a month all the time for some problems, then unexpectedly for me they brought on the day of the next repeated appeal, but not what is needed and underweight per ton of sand and crushed stone brought the most small instead of medium. I took at least something better than nothing, but it angered me, I wanted to shoot them for such meanness.
