Venus - Gazebo 10x12 Toit de polycarbonate

Beau look!

WHAT A WASTE! Never in a million years did i think that id be disappointed with a 2000 dollar purchase as much as this. theres a reason i spent this money on the set because i didn't want to go through all the issues with buying cheaply made furniture but here i am getting the same disgusting quality while paying top dollar. the bolts are made of garbage and strip as soon as you try to tighten them . almost 50% of the thread holes didn't line up. 4 panels came damaged and now because bolts are damaged they cannot be tightened and now 4 days later the middle is sagging. how do i go about getting this resolved. I'm not taking this thing apart for a return ! 4 days with 4 guys and i had to make things work with self tapping screws. the damaged panels are letting water in and I'm afraid this thing might fall into a hundred pieces on a windy day. definitely not worth the money. spent 2400 on it and about another 100 in parts to make it work
