Due to the advancement of repository technology, it only takes half a year for a team of developers to do the monthly work of one developer.
I first noticed they weren't automatically charging my card last year, after about seven months of receiving invoices that were still marked as unpaid. The fact I didn't pay any of them for seven months didn't seem to bother them, either. I think I managed to somehow get lumped in with all of their huge business accounts where payments have to go through a Process(tm) to get approved.
