Idiot son ran up an enormous (£100s) vodophone bill a couple of years ago that they eventually sent to a debt collection agency. He has been paying this at £10 a month and the debt is now around £200 but the debt collection agency now have returned this debt to vodophone as it's probably not financially worthwhile collecting, though no explanation was given.
Vodophone haven't contacted him yet to write off the debt or sent it to another agency...now 2 weeks. He can't afford to pay this amount outright. If vodophone don't contact him can they send it to court so he ends up with a CCJ? Any idea what course they are likely to take?
