Your gut feeling is bang on but you know this really. Move on mate. She's disrespected you IMO. Sorry, but you need to know you're just a weekly paycheck to her so this relationship you've built up is likely all in your head. She's made an offer out of guilt at messing you around originally then changed her mind when her business head has kicked in (time is money). She clearly doesn't value you as a client or respect you enough to honour her promise. You're at risk of seeming a pushover, woman like her will walk all over you if you give off this vibe. Sorry to be blunt; tough love.
Highlander has basically summed up everything to a tea.
Basically
I was recently offered a freebie by a wg to make up for a faff on with a earlier booking. I accepted and she was very insistent, a booking request filed and confirmed via aw.
1. She knew she had acted poorly and thus felt the right and reasonable thing to do would be to offer the freebie.
She obviously from the get go didn't want to do it. So then thought to try and justify doing it in her head, and try to make it somehow beneficial to her, tried to force the booking to be made via AW to thus ensure a good review and field report comes from you as a result on AW. (if you seen her for free, you would be more inclined to write a glowing field report)
Well the freebie meeting was cancelled on the day and 2 polite messages about rescheduling have been ignored.
2. On the day her WG mind kicked in and thought to herself, hang on, I am doing this for no money whatsoever. Fuck him. And so just blanked you and ignored your messages
if she is embarrassed and thinks id kick off or anything my only hope is she might see this post and realise I'm not fussed about the freebie but would like to continue meeting her. As it stands id say that is my best case scenario and the way I hope it turns out.
3. If you say and do this, then you are giving her an open invitation to treat you like shit on every subsequent booking. And it is unfortunately the case of she will do. She will take mega advantage and you will end up getting just a fraction of the service you received up until this.
The thing you have not mentioned that is really relevent to this is how long it has been since the cancelled booking and ignored messages. A week, two weeks, or just a few days? The longer it goes on the more obvious it is she has just blanked you and does not care (or want) your business.
The simple facts of the issue
a. She messed you over so badly to warrant a free booking.
b. She then on the day cancelled as she figured she is losing some money clearly thinking to herself she does not care if you never book her ever again.
c. She knows how wrongly she has acted, by the simple fact of her ignoring all of your messages. And there is also (depending on the length of time and how much she has logged into AW) no justifiable real life excuse (if she has never one logged into AW or just done it one or so days then maybe an excuse exists, if its everyday she has logged in then it was deliberate blanking).
d. If you go back now and start paying full price ignoring the freebie she messed you over with, you are in effect saying to her its open season to treat you like dirt and you will just accept it. And trust me she will do this from then on in.
The three options are.
1. Write a negative now on it all and move on
or
2. If its only been a short period. Wait longer and see if she responds (but if you are talking going over two weeks from this then you really are hitting at your answer to this)
or
3. Message her and say direct. I am starting to think you deliberately ignored my booking. If I am wrong please can you contact me to re-arrange it. And tell her if she did mess you around and thus ignores your message now that you fully intend to write a negative field report review for her both on Adultwork and on UKpunting based on the original issue that caused the free booking. And also the fact that she deliberately messed you around.
