“I took your advice … he has paid all maintenance owed ….”

Just a quick update regarding my problem with my ex paying the maintenance he owed.  I took your advice and contacted a debt collection agency which we use in work.  Today he has paid all maintenance owed and agreed to increase his maintenance payments to the correct amount.  I am in shock!  I wanted to thank you for your advice and for taking the time to help me I really appreciate it.
