I am an artist which Unamee contacted and asked if they could use two of my designs on their shirts which would be for sale on their site for a week. They sold pretty well. This was back in October, and they STILL haven't paid me.
First I was told I'd get paid in November, then they changed it to December, any other emails I have sent after that - which there were many - have been ignored. I will not keep quiet about their disgusting lack of customer service until I get paid.
And even when I do get paid, I will never do business with them again. My shop is called The Reverie if anybody is interested. I have a Teepublic and a RedBubble.
