Discontinued Stock and run around the bush for a refund!

I placed my order for a laptop on Monday, 6 December and received an email confirmation that my order was placed successfully. At the time of placing the order the item showed as in stock. When I had sent my proof of payment immediately.

I followed up on the online system the following day where my order showed as not paid. It still shows this status until today!

On 14 December I finally got this response:

"Good afternoon Mark

Kindly note the unit has been discontinued. Please advise if there is an alternate item or would you prefer a refund I do apologize for the inconvenience Thankyou Kind Regards Garth Botha"

I have asked nicely for my refund and met with incoherent responses out of context and that make no sense thereafter. It is now nearly 10 days later and still no refund. This is pathetic service from an online retailer. If you cannot deliver the goods or service, refund your customer, immediately! What is more, have the decency to call him when he asks you to!
