Double billed and no refund

I am very disappointed in the handling of accounts at zimbali lodge. They deducted R4000 as a holding fee. We spent R1600 instead of deducting the money spent from the holding fee they deducted and additional R1600. I do not understand why we must be inconvienced and be out of pocket while the hotel helps themselves to our money. This is unacceptable and no way to handle a business. I do not understand the point of the holding fee. I now cannot pay my bills because im out of pocket. What horrible handling if accounts.
