Makro lost my order and is failing to process a refund.

At the beginning of February I purchased a 55" TV from the Makro online store, delivery was scheduled for the 14th of February. Makro somehow managed to lose my order. I e-mailed them numerous times asking for a status update, all e-mail correspondence was ignored. When I called their customer care line I was promised that the issue will be resolved by no later than the 21st, the TV was at a store and will be dispatched for delivery. After being stuffed around for another 2 weeks , and a host of ignored e-mails / service requests, I finally cancelled the order on the 28th of February (***). I am now waiting for Makro to refund me R 9139.90 , however they are ignoring all my attempts at communication with them . I did manage to get through to customer support today (7 March) and was informed that they do not know when I will be refunded. Apparently, according to customer care, finance has a back log of refunds and they cannot confirm if I will be refunded any time soon. This is completely unacceptable, as Makro was very quick to take my money, then failed to provide the purchased items, now their finance is uncertain if they can refund me.

I have placed an order for a TV with a different retailer, however Makro's incompetence is preventing me from making the payment.

I am prepared to take legal action against Makro.
