Time to get a response from lost property email?

Firstly I'll start by thanking everyone that was there for an amazing weekend. If I could spend every waking day in that Green Man bubble I would do. There isn't another festival like it!

Does anyone know how long it takes to get an email response from lostproperty@greenman.net email address? I managed to lose glasses and sunglasses on the first day and my eyes have barely recovered enough to stand constant contact lenses! Plus the expense of replacing them...I'm holding off on doing that until I know whether they were handed in or not. Emailed yesterday but not heard anything back yet.
