Order cancelled once again after payment has been received

I placed an order and paid for it. Zando then cancelled my order. I notified them and my order was reprocessed. I have been waiting all this time for my order to be delivered. I went onto my profile and noticed it has been cancelled once again. I have sent numerous emails and no response whatsoever. This is absolute bad customer service. I want a full refund and if this is the case I will never use their service again.
