To send my ex a message saying if he doesn't sort out regular contact with DD within a certain timeframe then I will no longer be facilitating his random and sporadic short contact times.
Long story short- It's been 3 years, he pays no maintenance, hardly ever sees DD and is a nightmare to get hold of!
I will also say in the message if he wants contact after failing to sort it out within the timeframe he can go through a contact centre
