Unfortunately, it is not possible to change an open booking request that has already been sent to the service providers. This is mainly due to the fact that your selected service providers may not be available on the changed date and therefore a new selection must be made.
If you would like to change the date or time, please send us an e-mail to kontakt@helpling.de or give us a call. You can reach us Monday to Saturday at +493056839280, from 08:00 to 17:00.
