The capper for me was when I arrived home late one night from a long day of work and there was a fed ex from them on my doorstop.  A recording, with check, for a parish 2 hours away they wanted done the next morning.   I had no prior knowledge of this recording, and hadn't agreed nor had I the time to get to that parish. When I finally reached someone at Servicelink to discuss the woman was defensive, offensive and her logic was they didn't have time to call all their vendors to inquire about their availability.   (they also, apparently, didn't have time to pay without constant nagging)

That's when I told them to not darken my door again.  Much more trouble than it was worth, and they had the attitude I worked for them exclusively - though they didn't want to pay.
