No refund happening as promised!!

I would like to utter my disgust with the customer service that I have received from this Hotel!I made a booking for my family for December and made payment for the full amount on the same day.The Hotel then changed their rates the very same day,although the amount that I paid in full was advertised by them online as a special for that day when I booked and paid.The new rate now advertisedon the same day was R3300 cheaper than what I have already paid the hotel on the same day.I then phoned the hotel to query this huge difference,and they agreed that I should cancel the initial booking which I paid for in full,make a new booking online again for the lower amount;and that they would refund me the R3300 overpayment as soon as the funds show in their account.I made the full initial payment on the 14th of March,and got confirmation that they have received the funds on the 16th of March,and that they were busy processing the refund.....To daye I have sent 17 e-mails asking about my refund,and all I get told is that they are processing it....!!Yesterday I received a response that it will be done within the next two weeks!!!How can a simple refund of my money take almost a month???
