Manipal Hospital — Delay In the appointment

Our appointment time was 2:15 with doctor avnesh seth gastrologist but that appointment is delayed by half an hour which is not acceptable. If there is a delay hospital should have informed us about the delay so that we communicate accordingly. we are waiting for the appointment from past half an hour and lady at the reception is saying it will take more time. I need to complaint about this please consider this on high priority otherwise I will escalate it higher authorities.
