Fortunately, this is my first bad experience purchasing through Waifair. This vendor/SIMPLI-HOME should not be selling through your website. 
The company does not seem to have any quality control on their production line, and they are using very cheap “poor quality” accessories that breaks easily. I purchased my own accessories and had to take the cabinet apart then rebuild it - it took four (4) hours. I sent them the invoice. and I am waiting to be reimbursed.  Thank you,
