I'm a photographer. A past client emailed me about two months ago and inquired about scheduling a shoot with me on the 15th of May.
Me: I'm available on that day. However, given the number of subjects that'd be involved my rate will be higher than last time. Your last shoot was $750 but this will be $1000. Is that all right?
No response. Several days later, I sent a follow-up, once again asking her about the increase and rate and that if it'd be alright and within budget.
Again, no response.
Several days after that, I sent one final follow up. No response.
A few weeks later somebody booked me for a much larger job to take place that day. Fast forward a couple months, where the shoot date is now half a week away. At this point the client that had ignored me previously on three separate occasions sent me a shot list.
Me: I'm sorry, but I'm booked for that day. I tried following up with you several times and received no response so I assumed you weren't interested.
Predictably, she flipped out, and sent me a flurry of emails requesting I call her (she's the head of a department, so she probably does this all the time with people that actually have to call her, woe be them), that it was wrong of me to cancel our shoot and give it to someone else, etc.
Me: You didn't even call me to cancel the shoot!
...As if three emails weren't enough, it's on me to start calling the client as well.
She explained that she was fine with the rate and that that was why she sent me the shot list (half a week before the shoot, and two months after ignoring me). After I copied and pasted the three confirmation emails I'd sent her into my response, she surmised:
Client: There must be something wrong with my email server.
