New, but leaking, rusting canopy !

Was hoping I wouldn't need to resort to a review but has now been nearly 3months without any response from Treehaus and seems that I am now sitting with an expensive new canopy that is already rusting. Had a few problems with the canopy when it was delivered. I was told problems would be sorted out so I was happy to trust them and make payment. After payment unfortunately I'm on my own it seems with a canopy that is useless to me.

Won't go into the minor problems on the canopy but main issues are the bad welds where water is leaking in at numerous locations. Within 2 months of purchase the canopy has started rusting at most joint locations on the inside. Really shocked that a business does not take pride in their work and sort out these mistakes immediately. Before my order I had also specifically asked if the rear door design will secure the load bin flap, was not going to order a design that allows flap to be open with canopy closed . This ended up not being the case either so can't lock canopy. It's of no use to me now, was needed to keep gear safe and dry.
