HORRIBLE CUSTOMER SERVICE AND *******!!!

After speaking with a salesperson and assuring me I would receive my order within 24 hours, I received it much later. I asked for a refund, they said I should pay to send back the items, which I did, the box was still unopened, now I can't get a hold of them for my refund! They are not answering ANY calls or emails (I have sent over 20 mails). I have been trying for over 4 weeks now! HORRIBLE CUSTOMER SERVICE!!!
