These guys have been on our do not use list for years and we haven't missed them a bit. Well, a recent system upgrade somehow erased all of our settings and an order slipped past our dispatch without our accounting department realising. Well its now at 93 days and no sign of payment. Got hold of a guy that claims to be the owner and when we ask "why has this bill not been paid". His answer was "because he hasn't been paid yet".
So... we've given him until Tuesday for us to pick up a check. They've been told after that, we will contact his customer directly.
