Individual — Non availability of staff

I am a regular returning customer of VLCC various weight management programmes.I booked an appointment at VLCC, Marine drive, Mumbai centre at 0930 hrs on 28.07.2022. I reached there exactly at 0930 but no one was present.As it was office time for me also, I could hardly afford to wait for 20 minutes ( as we were asked).I, alongwith my wife came back unattended and carrying a bad experience of an institute, which we had always held in high esteem due to its high standards of professionalism.Would like to shift to other options available now.Thanks
