I agree you should answer them, but they are not allowed to harass you - I'd tell them that late evening phone calls are not acceptable. They also take very little notice of anything you say, as far as my experience goes. Before I actually went bankrupt, I was trying to negotiate a lower repayment schedule with my creditors. It wasn't that they refused - they simply ignored me and made the same phone call the next day. In an odd way, it's a relief just to tell them 'I'm bankrupt'. (Not that I'd recommend it!)
