If it says Black Mass, or used to say Black Mass and isn't working I'll fix it. I don't care where you bought it.
Send me an email and we'll get it taken care of: firstname.lastname@example.org
If it's clear you did something very very wrong and broke it, I might have to charge you to fix it but otherwise, I'll just fix it.
