Worst service

I absolutely love Crocs and we jumped to the opportunity of ordering their Black Friday specials this year. We drove all the way from Krugersdorp to the store in Woodmead, only to find that they did not have the same specials in-store. We were dissapointed, but the staff there was excellent and we decided to order online. I placed my order on the 25th of November and paid via credit card. I immediately received an email confirming the order and stating that I must allow 3 working days for delivery. Perfect! It has been 7 working days today. I am umable to get a hold of anyone via telephone. The phones just keep ringing. I receive no feedback via email (I have sent 3 emails to all 3 'support' email addresses). I have even sent 2 messages on the Crocs Facebook page, but I am getting no feedback from anywhere. Today I received a courier delivery out of the blue with exactly half of my order. Will I ever receive the other half? I will have to wait and see. I am beyond frustrated and extremely dissapointed
