Soul Thai Centurion scamming customers

I phoned in to the Spa and booked a massage for 60 minutes for myself and my partner, for 11:30 to 12:30 Saturday the 24th but the massage was finished by 12:10. When I complained at reception I was told that the receptionist had put the wrong time for me in the book. She booked me for 11:15 but they still made me pay for a full 60 minutes even though the mistake with the booking was on their side. The ladies at reception were very unprofessional in handling this situation, I was told that they had other customers to attend to already hence my our massages were shortened to 45 minutes. I was promised a call by end of the day yesterday but the manager never called.
