Disgusted and dissappointed

I have made a booking at Zebula lodge for 2 nights at a price of R6200 per night. After booking was confirmed and deposits paid, 3 days later I get an email from bookings.com saying that over that period of time I have to book 3 nights and instead of paying R6200 a night I now have to pay R7000 a night! I said Im not accepting this and want a refund and now they are offering me accommodation for double the price snd not getting back to me regarding a refund!!! Very disgusted!!!
