They definitely need to get better at the assembly instructions. Better yet-the quality of the product itself would help. You can’t properly assemble it because the “holes” are actually indentations that you need to dig into just to insert a screw or the instructions don’t clearly tell you which side up or out to face the shelves 
/doors so you can tighten screws/joints. I’ve had this thing partially assembled in my house so long I have missed the window to get any type of assistance. My first time ordering from Wayfair and I place a super large order yet I foolishly didn’t read their return/exchange policy. *insert eye roll* yes, they charge you to return AND exchange. I’m sorely disappointed. I really don’t know if I’ll be able to finish this cabinet on my own. If you purchase it, you may have to actually drill deeper holes into it yourself just to get it done. That’s what it’s looking like I’m going to have to do.
