I saw this on the Writersroom and thought it might be of interest.
"Recorded for Training Purposes is a sketch show for BBC Radio 4. Its remit is to be about "modern communication" - a wide brief, that can cover anything from straightforward sketches involving unhelpful helplines to parodies of modern types of TV/Radio."
Sketches should be sent to email@example.com by November 17th, 2008. See the Writersroom for full details of what they are (and are not) looking for.
Having worked in IT and Customer Service jobs for a huge percentage of my working life, I hope I will be able to come up with something. Drawing a blank just now though!
