awful service from supervisor

Very Bad experience. i called ********** 456 at 9am to book. When taking my booking the lady asked my name and number. i said we were four and would be there at 7pm. We got to the line and we were fourth and then people from the back formed a new line saying it was bookings whereas we also had booked and ended up being two booked lines. . When we got to the front the lady Nompulelo said we had no booking. I explained what had happened and that I had drove far she said I must have called the wrong number. I took out my phone she showed her the call time and duration she said she was doing bookings and it was not the right number. She was very rude to me. I called the number and at the reservation table in front of me it rang and someone answered . she insists that isnt the right number. when I called I was told my booking was confirmed. i called the same reservation desk and was not told to call a office. She still was very rude and says well there isnt a booking and Im dialling the wrong number despite someone answering at the reservation desk in front of us. ********** 456. Eventually a guy had to come and say he will make a table for us. No apology and very rude throughout. Worst is she is a supervisor. Surely staff are trained. We ate but I was agitated already so didnt enjoy my evening. Our waiter Sheldon Lee on the other hand gave us excellent service throughout the night. Based on the service from Nompumelelo I will never recommend what is a good vibe restaurant . you cannot be so rude to a customer especially when you at fault. I was highly disgusted
