If a debt collection warning is not paid within the deadline, the bill gets sent to debt collection.
We initially send out a normal bill, but if that bill is not paid within the deadline then we send a debt collection warning. If that bill is not paid either, the next step is debt collection.
Contact the debt collection agency you have received a bill from, if you have any questions about this.
Here is the contact information to the various debt collection agencies:
