WORST CUSTOMER SERVICE EVER

I ordered a Magic Easy Spin Mob I received it and it was defective I Paid for the courier and returned it for a replacement and was told that I would be refunded for the courier chargers.. I was asked for my bank information, sent everything and today I have been told that I have been sent a check instead of a credit to my account for the courier charges. My replacement never shipped so I asked for a refund, there are abt 17 emails back and fourth and no one in customer service seems to have access to any of the information every time I call there is a new person answering the call having no Idea of what is going on nor do they see any emails sent to them. Everytime I ask for a supervisor I am refused and even if they do agree to transfer the call they would just keep you on hold and disconnect the call. I have been told that it takes 15 working days for a check to reach me when the item itself takes only abt 5-7 days. ONCE I DO GET MY MONEY BACK I AM NEVER DEALING WITH THEM AGAIN… PLEASE BEWARE!! AND DO NOT PURCHASE ANYTHING FROM THEM!!
