Thanks for reaching out to us with your concern. Please allow me to apologize for any inconvenience this may have caused. I checked on the Dell South Africa website and as you said it routed me to the re-seller. Check with your bank if the Visa card was charged. Please call Customer care using this link and check if they have any information about the order: http://dell.to/183tLH3
You could also provide the Order number, Customer number, name on the account through Private message so that I can check at my end. To send a Private Message, click my User name and Start Conversation.
