ITIL - problem management

[Ditto]

Any ITIL experts out there - I'm a rusty on the details!

 

We use progresso and few months back they announced they would be introducing the ITIL framework to help with their customer support. The situation I am in is that 'Cases' (perhaps should be called incidents) that I have logged after agreeing there is a 'Problem' and passing it on to their development team. The issue I have is I have no way of tracking the problem going forwards. Can someone remind me what the process should be that keeps me as a customer in the loop and what part of the ITIL framework covers this?
