Sorry, but once you book the service it will not be possible to modify the collection time. Once carrier receives the collection request, they organize their route according to the number of collections in the area, therefore it will be not possible to make changes.
If you need to add any comments regarding the collection time, you can contact us and we will send it to the carrier.
Also is not possible to reduce the collection window and choose a precise collection time.
If you need to reschedule the collection to another day please get in touch : Reschedule Pick up
