back story: i did some freelancing projects for a certain company (client support, installing printers, configuring email etc.). the work is like 5 hours per week. i get getting my money but the client stopped giving me my dues. the reasoning is, have a lot of stuff to do etc. unfortunately, there is no written agreement. (yeah yeah, i know. but for a few bucks/hr, i didn't think this would be necessary at the time) any suggestions what to do, to get my money? i have his passwords. what if i change his email, ebay, etc. passwords, so he stops getting emails and other stuff? thanks a lot.
