Terrible service from ZANDO

I placed an order on the 29th of november (black friday). I called and sent numerous emails asking when my order was going to be delivered and I did not get any assistance. The stuff was delivered on the 29th of december and they sent me wrong stuff. Since then I have been sending emails asking them to do a refund as my order does not appear on their new website for me to do schedule a refund on my own but I haven't received any response. Their phone doesn't work and seriously I need my money back. zando service is unacceptable. Please just refund us our money and close down because clearly you do not know how to do business.
