TERRIBLE customer service. They say FAST shipping on their website. I placed an order and a week later after I put in my order I contacted customer service via email support. They told me that they had my order but no update was available. That's it. No apologies for not shipping... nothing. Then another week later I get an update to my ticket saying they were canceling my order altogether because they didn't have stock in what I ordered. Now it has been a week since they said they would refund me and still no refund. Absolutely terrible customer service and business practices.
