Don't deal with this company

Used http://xoc.co.za/index.html to place an order for a package to be delivered. Went to Payfast payment gateway, paid using credit card. Then website froze - so a payment went through but then nothing... Transaction disappeared. Try contact support, can only do so by logging a ticket. Did so, got an acknowledgment email and then nothing. I will now have to use another courier company and pay again. Trying to reverse the payment to XOC
