I run classes and I am experiencing an issue where customers are double booking themselves and taking 2 slots in the same class.

In my testing it is not possible for a customer to book a new appointment for a class they have already booked, but it is possible for them to reschedule an existing booking to a slot where they already have another booking.

How can I prevent this from happening?

Hi Marko

The issue has happened multiple times in the last few weeks on my client's live site. I was also able to recreate it on my test site.

I have attached a screenshot showing the same customer booked 3 times for the same appointment, same time, same employee.

It happens when a customer reschedules an appointment. It can happen with the same employee and same service when multiple slots are allowed per appointment (max capacity > 1).

Steps to recreate:
- Set up a service with max capacity > 1
- Assign the service to an employee and set the employee's available hours for the service
- As a customer, book an appointment for the service on the frontend
- As a customer, book a second appointment for the same service on the frontend
- As a customer, log into the frontend customer panel. In the Appointments tab, reschedule the second appointment to the same time as the first appointment (it allows you to select the same time without giving an error message)
- In the backend find the appointment in the Appointments section and you will see the customer is booked twice for the same appointment.

I can provide access to my test site if required.

Hi Marko

I tested, and the issue is not resolved yet. 

In the frontend customer panel it still allows me to reschedule an class/appointment to another time slot where I have another existing class/appointment, which books me twice into the same class.

See new screenshot attached.

Hi Marko,

You are not following the steps I provided to recreate the issue.

I know that it is not possible to create a "new" double booking using the step-by step booking form, which is what you show in your screenshot. 

It is possible to create a double booking when rescheduling an appointment using the front end customer panel.

Here are the steps to recreate the issue with a bit more detail, using an example services from my test site

1) As a customer, book a new appointment for a Reformer Pilates class using the frontend step by step booking form (Time1)

2) As a customer, book another new appointment for a Reformer Pilates class at a different time using the frontend step by step booking form (Time2)

3) As a customer, log into your frontend customer panel. In the Appointments tab, you will see the 2 new appointments you created - Time 1 & Time 2

4) Click on the 3 dots to the right of Appointment Time 2, then click Reschedule (see attached screenshot)

5) In the date and time selector, choose the same date and time as Appointment Time 1

6) Click Continue and it will reschedule the appointment and create a double booking without giving an error message

7) As an Admin, log into the backend and find the appointment in the Appointments section. You will see that the customer is booked twice for the same appointment (see attached screenshot)

Can you please test again using these steps and provide a fix.

Hi Marko

Thanks for the update. Are you able to give an indication of what release the fix will be included in and an estimated timeline please? I need to let my client know what to expect.

Thanks
Daniel
