He should not be calling you. You are not a dealer who just sold a used appliance with a 3 month warranty. Once the exchange is made, end of story.

Yeah I know at first I was willing to help out, trying to be nice, but damn no good deed goes unpunished, LOL

Another email just then, asking how you change the globe in the launcher button, probably another one that came loose.. but FFS, he can't even work out how to get to the globe in the launch button without feeling the need to contact me again??

Ignoring this one altogether, if I keep responding I am just encouraging him... See how long it takes to call me if I don't answer his email?  

OCPD??
