Once the DPE made a schedule,

you can check by 'Refreshing'

Once you make a schedule following the above,

you will receive an email that includes all the details.

However, if you cancel after the specific time frame

that a DPE set, you cannot receive your deposit.

Also if you want to reschedule, you can only

do so within the specific time frame.
