Disappointing experience

I subscribed to Love Goodly using the $15/month for 2 months promotion. They sent me a survey to choose what type of necklace I wanted in my box. I submitted the survey on time but was sent a necklace that had not even been advertised as an option. After numerous back and forth emails, Love Goodly essentially blamed me for their mistake and wanted me to pay return shipping in order to get the necklace I had actually picked. I was then told that they would just go ahead and send me the right necklace. However, it has been two weeks, and nothing has been resolved. Proceed with caution.
