Finally caught up with Model's Own's customer service (had to forward my email to them because of their moving offices) and they've taken care of the issue and will be sending me the three polishes that are missing from the Beetlejuice set.
While it's been a pain in the ass having to wait nearly 2 months for all of the polish I originally ordered, their customer service IS good about things (they could have just brushed me off and told me there was no proof, etc, etc, instead of sending the missing polishes and not asking back the ones that were sent by mistake.)
I will definitely be doing business with them and look forward to being probably the only nail tech in my area (hell maybe even all of Florida) that uses Model's Own.
Heck, maybe in the long run when I'm working at a salon that allows it or running one of my own, I'll even see about being a distributor. I really do love their polish a ton.
