STEAM ON MAIN (SUGAR HOTEL) WORST SPA TREATMENT ESTABLISHMENT

I had the worst experience yesterday at Steam on Main Spa (Sugar Hotel - Green Point). I made a booking for 2 more than a week in advance for Wednesday, 12 October. Lelo took my booking and confirmed all was in order. When I got there 15 minutes before the time I was told another lady is waiting for the same time slot. I told them I don't know the lady and that my friend arrived that was going to have the spa treatment too (my booking for 2). The unknown lady that was there made a booking for a spa treatment for the same time the day before the time (11 October). Because there are only 2 spa rooms I was told that there is only room for 1. I refused to accept it and said my booking was made more than a week before and the other lady a day before so it was just proper to let my friend and I have the booking slot. I was told in a very unprofessional, unfriendly and rude way by Lelo that she knew she made a mistake by not diarising the appointment but we cannot have the booking. I refused to cancel for another day as suggested by Lelo. It took more than 20 minutes for the issue to be sorted out when the manager (his name was not given) spoke to the other lady who made the booking the day before the time. My friend and I were eventually told that the spa rooms were ready for us. We received no apologies or interaction from the manager. Our spa treatment was supposed to be for 1 hour but because it took the staff more than 20 minutes to sort out the issue we had a 40 minute spa treatment even though I paid for 1 hour's treatment. This is the worst service I have received from such an establishment.
