Never, never buy from this lot!

On the 14th of December I bought a specific item I could only find online at Homechoice. I placed the order and then processed the payment for R 605.82. The money was taken from my account but on the Homechoice website the order still showed outstanding. I queried this with them and sent them the proof of payment and requested a refund as they are unable to process the order. They asked for the proof of payment again but I cant get anything out of them as it has been forwarded to the accounts department to "find" the money. How difficult can it be. I simply want my money back but this lot is incapable or unwilling to refund the money.
