The laundry centre was delivered with missing the bottom parts which caused the floor damage.
Of course, I reported it to Costco, but they through everything delivery company. And even I was mentioned that I had to call the manufacturer to order the parts by myself. So they did nothing. The delivery company stopped responding to me once the incident was reported and got back to Costco, he would contact them and get back to me. Nothing happened after. Got back to Costco to talk to someone else, however, what they can do is contact the delivery company to push them to contact me. If they don't take the responsibility of the floor, done! The guy I just talked to clearly said Costco won't take this responsibility. They just sell the products and don't take care after.
This was my first time buying the appliance from Costco.ca but I'll never shop again.
