I do feel the bad feedback is slightly unfair to be honest. but what can i do?
To be honest if the circumstances Iain describes are accurate (and I don't believe he'd lie about it) I'd probably have done the same. And I've never left anyone bad feedback before either.
As to what you can do about it - that all depends on what you can sort out with Iain. I have known models to rebook with a photographer following bad feedback with the result that the bad feedback was overwritten with new good feedback. But I also know that some photographers have just been burnt twice when they've given the model a second chance.
Sane and sensible people can usually reach a satisfactory resolution but it looks like the ball's in your court at the moment.
It is often difficult/impossible to find another model suitable for the job at a day's notice. Had it been a couple of days' notice then something might have been possible.
In these email situations a phone call is sometimes better and more reliable.
However I guess it may not have actually cost Iain the job. It should have just delayed it a few weeks, which admittedly may cause a cash flow situation downstream as there would be a delay in the flow of cash for the job.
Hi Iain, you are going to so hate me but i not going to be able to come tomorrow,
Dated the day before???????
You wrote that message in response to the message I sent you that day to make sure you were coming...as I say, I suspect that had I not initiated contact the day before the shoot you would not have got in touch at all. You had plenty time to get in touch with reasonable notice.
I would also advise you strongly to put the spade down and stop digging as no good ever comes of washing dirty laundry in public.
