I’ve played around with QoR but the price is a deal killer for me (there are so many fabulous brands for much less) and some of the colors can be a little overpowering and cloudy. But QoR Cobalt Green is one of my favorites! It does sound like you got a lemon. Every single time I’ve reach out to them, their customer service has been spectacular. You’ve probably gotten it worked out by now, but if not, give them a call or email.
