IKEA Canada

This faucet came with a faulty nut, wrong size. I requested on 2 occasions that a new nut be sent. Both nuts sent were wrong size. The nuts are a special thread only IKEA uses and cannot be purchased at any hardware store. The third time they sent a package of replacement parts, but again the size of bolt not compatible with the faucet. After the third time I requested a replacement faucet be sent. I am still in negotiation with IKEA. Worst customer service I have experienced ever. 1 hour on the phone with the most recent conversation. This has taken me many hours with no resolution.
