The payment schedule cannot be changed by Goboony. This schedule is automatically created when you submit a booking request and therefore it cannot be manually changed.
If you are unable to make a payment, we suggest that you move the booking to a later date, this will then shift the dates of the payment schedule. To change your dates, you may contact the Advertiser via the booking page and send a change dates request. The Advertiser will then have 48 hours to accept or decline your request. Once accepted, the dates of your booking will change, followed by the payment schedule.
