Terrible service at CaCell

Terrible customer service. Purchased an item on the 20th Jan, waited about five days but no communication. I cancelled the order and I'm still waiting for the refund to be sorted out! I have sent many emails, called the call Centre numerous times and even SMSed but no joy. I have now been billed for this item on my Mobicred account!! This is ridiculous. I need to be reimbursed.
