I ordered linkers for my Canvas system and what was sent was for the triangles and would not work. Dealing with support took DAYS for a response but finally they agreed they were wrong and sent a replace that took at least another week or so before I received. What came was again the wrong ones. I emailed support back on the same ticket. ABSOLUTELY NO RESPONSE. I tried again days later. Nothing. I then went to the website and opened a new support ticket. Again, nothing. Meanwhile I have a huge Canvas project half completed on my wall for two months. I got so frustrated I just ordered another new set and a week or so later, I finally got the right ones. I love your product but your support leaves a lot to be desired. If I didn't already own an entire wall of Canvas, I would have just moved on to someone else.
