WORST SERVICE AND WORKMANSHIP EVER!!!

We had them replace 3 windows at our house today....pathetic is not even the word!! Told them that our dining room windows that needs replacing is tinted so the new windows needs to look the same. After installing the windows and cracking our tiles under the windows we saw that there is no tint. Our other window they chipped out the window and we have pieces of glass laying everywhere. They removed our clear burgular bars to fix the window and came back just before 20:00 tonight to put the rivets back into these bars after the broken windows were removed. They saw that the rivets they brought are too small and left all the wrong sized rivets on the floor and got in their bakkie and left and we asked them about the tint and he had a dum strucked look on his face and continued reversing out of the driveway. I am livid!! The worst of all is that this was an insurance claim. These guys are absolutely useless... I won't even recommend them to my worst enemy!!!!!!
