Vindu montering

They have sent a team of 2 person. They do not understand english/norwegian. Initially paid by hour. One worked good, one keep one hand in the pocket and cigar in the other. We agreed to continue on fixed price so I will not have to worry about productivity. I indicated fails on the structure they built for the new bordkledning and they have fixed the problem. They also installed some windows that are look good. Because the initial scope of the work extended, I wanted to have a contract where to write all that it has been done in case of any future fail to have some warranty. The manager refused to make a contract. They only issued a bill that I have paid. I will not work with them again.
