Angry "cupping" problem in newly laid bamboo floor

We installed bamboor floor in 2 rooms and 3 hallways over slab foundation. Within a few months, the floors are cupping (both sides of each palnk are curling up) all over the house. Moisture testing showed that moisture is coming up from below. This was unexpected since we live in desert like dry climate. Has anyone have similar experience? Who's at fault? Manufacturer? Seller? Installer?

Was a moisture test on the slab done prior to the installation?

What type of installation was done? Nail down, floated, glued?

Is this a solid bamboo, engineered or laminate?

Was a vapor barrier installed over the slab?

Is there proper plastic barrier under the slab?

Whoever installed the floor, accepted the conditions of the concrete, especially the moisture vapor levels, and took a big risk, by not performing the required moisture tests.
