@craiggrannell If they’re cagey about helping you, then chances are they’re just fobbing you off for some reason. Either they’re delaying paying (because they have no money, probably) or they’re going to see if they can kick it so far down the road that you’ll give up.
In which case, you need to get firm and inform them that you will need to start formal recovery proceedings to ensure you receive the money you’re owed.
