I do freelance writing for varius people, and one company has always been awful - I have not worked for them for ages, but finally did some work for them and was told that the terms of payment were 40 days after publication. This turned out to be 40 days after theendof the month of publication, then they said that because the publication date had been towards the end of the month it would count as the next month. Which should have made it the 10th of this month when they paid up, and they still haven't done so. They are 'busy' apparently, and it will 'probably be some time this week'.
Is there anythign at all I can do?
