I was making a Wordpress site for a client. He requested changes every single day and made crazy requests like removing all logos from the site. I also provided some PR consultation, giving them strategies for dealing with their EXTREMELY negative customer reviews that highlighted their terrible service.
I sent my invoice and three days later received this message:
Client: I'm not paying this. Your SEO wasn't good enough.
This was strange, because they hadn't given me ANY content that would help their SEO ranking. No images, no text, no nothing. ALSO, I new for a fact they'd paid someone else $800 a month for SEO but there was nothing in place when I was hired on.
