I only received two rings instead of three. And one of the two rings is not one that I ordered. I have emailed twice for an inquiry into what can be done about it, but have not received an answer back. I am unable to find a customer service phone number to speak with someone. It says there’s a 90 day moneyback guarantee but even if I were to try to return it, there is no process listed for this. I was disappointed because I ordered two of the bands so that I could wear to work
