I have created two services for example phone consultation and face to face consultation. If I book phone consultation for 27 July at 6:00 PM, it should mark it as booked. Problem what is happening is that if I go back again to book another phone consultation or face to face consultation then it is allowing me to book for 27 July at 6:00 PM. I have the put the daily limit for each service as three. If I put the daily limit as one then, between 6:00 and 8:00 PM it will not let me book anymore service. I have created 20 minute slots between 6:00 PM to 8:00 PM which can be booked by any of the two services. Please let me know what the problem is as once the service is booked for 6:00 PM then it should not be available again for the same day
