Disgusting Accommodation Business Practice

I made an accommodation through Booking.com for a two night stay at Clubmed 23, in Hibberdene. I was contacted two days before we were due to arrive to advise that an administrative error was made with the price and we would need to pay an additional R1000 to keep our booking. Again, this communication was received two days before our due arrival and is disgusting business practice. If I could have given negative stars, I would certainly have done so.
