So mad at Levolor right now

I ordered 2.5 inch wood slat blinds. A very nice product, custom-ordered. I did not order installation because, frankly, I enjoy doing home improvement stuff.

I am so disappointed with Levolor right now. My blinds were:
1. Missing a "tassle" (the wood thing at the end)
2. Missing two screws for the middle support
3. And this is the kicker: the cord lock is faulty. They are trying to feed six threads through the mechanism seen here:


Just doesn't work fellas. So I have spent about six hours hanging these #$#)$ blinds and they are completely defective and useless. So mad right now.
