How much have you paid prior to receiving the warning?

Be sure to communicate with them and If you’ve been given the chance, I’d recommend meeting them in person.

I don’t know exactly how that Uni operates but if this is the first warning then you’ve probably got some wiggle room to negotiate a payment plan. The action to close her University account is often what happens when students fail to respond to the warning I.e. the University sees it as a good way to get students who have previously ignored communications to come to the surface
