I've been doing some work for a client (web and graphic design) and they've been an absolute nightmare to work with. I always charge 50% deposit which is non refundable once work has started, I delivered the complete project to them and they were really happy and said 'I'll pay the final invoice today' yeah right. This was the last time I heard from them, after numerours calls and 'payment reminder' emails, I sent an email to them reminding them that until they had paid in full the design and site remained the property of my company and that they should clear their balance to avoid any disruption to their website. Five days later and still no contact I removed the site and replaced it with their crappy original site. 10 minutes later, (and I do mean 10 minutes!) I had a payment confirmation email from paypal and an email from them with some lame excuse about being busy and demanding I restore their website. Just had to share the story, worst client I've had so far!
