# FAQs & Contact

Quick answers to the questions we hear most.

### Booking an event

*For users who are trying to book an event and have questions, look here!* 

<details>

<summary><strong>I don't see any available slots. What does that mean?</strong></summary>

In almost every case, the event is genuinely fully booked. Slot supply is controlled by the organising agency, not the CalSG team — reach out to the agency or event owners directly if you need a slot to open up.

</details>

<details>

<summary><strong>A slot showed as available, but I got an error when I tried to book it.</strong> </summary>

This usually happens when someone else books the same slot moments before you, or your view of the calendar is slightly out of date. Refresh the page and try again.

</details>

<details>

<summary><strong>I'm not receiving my OTP.</strong> </summary>

Check your spam or junk folder first, and make sure your email is typed correctly. Wait a few minutes and try again, since delivery can occasionally lag.

If no one else at your agency can log in, raise a support ticket [here](https://form.gov.sg/63fc4348fff5120012b6cf28) so it can be escalated.

</details>

<details>

<summary><strong>How do I cancel or reschedule my booking?</strong></summary>

Check your confirmation email to cancel or reschedule your booking. Some events set a minimum-notice period and don't allow changes at all; if that's the case, contact the event organiser directly.

</details>

<details>

<summary><strong>Can I combine multiple time slots into one booking, or see who else has booked a facility?</strong></summary>

Not at the moment. Each booking covers a single slot, and attendee lists aren't visible to other bookers. This comes up often enough that it's logged as a feature request.

### For event creators

<details>

<summary><strong>How do we ensure that slots for our event get booked fairly? There have been instances of suspicious activity where all our slots have been booked within seconds of release.</strong> </summary>

In this instance, two things help:

1. Turning on a per-person booking limit if your event type supports it
2. Using Singpass-verified booking so one person can't re-register under multiple emails.

Both settings can be turned on in your event under **Settings → Singpass**.&#x20;

<summary><strong>A staff member who managed our booking page has left. How do we get access?</strong></summary>

Contact CalSG support [here](https://form.gov.sg/63fc4348fff5120012b6cf28), and provide us with the event link and the outgoing and incoming admin's details.
