Lezz I was finished in a few hours, while I do not know when the banks are processing something like that. That would mean that I have to keep money on both the old and the new bank account to prevent the trash. Now I had an overview and could switch immediately. I could also see exactly what was happening and when.
The transfer service is fun if you are bad with forms and if you do not have an overview of all parties with whom you do business. From my work I know that there are many people (do not be alarmed, some 70% of the Dutch have no overview and / or is bad with forms) who suffer from it and for whom the service is a godsend.
I (luckily) do not belong to the target group and like to keep things under control myself. It was also a natural moment to quit some things (subscriptions) that I do not really use, so immediately a cleanup.
