Homechoice will take your money, but not your order

On 9 June I placed an order on there website of nearly R4000. Upon check out the payment failed. I received a message that there was an error with the payment system and that I have "NOT BEEN CHARGED". I was trying to pay with my credit card. I have obviously also not received an order number, as the payment failed.

I repeated my order on 10 June. It was successful. I placed order ***5.

This morning I checked my bank statements. I have been charged for both orders.

I took this up with customer care. Even attached transaction logs of my credit card that indicate two payment. But still Homechoice insists that they only received one payment.

I feel cheated.
