What am I doing wrong?

[Peekaboo]

Who will be watching the children while the Mums are watching the thermomix demo? If if were you, I would skip this week. I would hate for them to take advantage assuming you will be watching ALL the kids for them!

And in regards to the original question from your first post, you aren't doing anything wrong. It's them, not you. I would find somewhere else - do you have a local library or recreation centre? They usually offer a weekly activity for the little ones.

Lol the kids will freak out because thermomixes are so loud! At playgroups I've been in, they actually make a point of telling you (in the short handbook) when you join that it's not an appropriate place to flog your new "I don't want to go back to work so I'm doing direct marketing" strategy. As you're finding, it's a great way to turn people off!

Time to move on and stop letting it affect you.

I would move on. I had a very bad experience due to sticking with a group that became unwelcoming (it started OK, but a new member turned it sour).
After that I decided that any group that I did not feel OK at, that I would move on. I found when I moved, that it was helped. I gave groups ago, a couple worked well for a long time and there were a couple of others that I got the vibe very quick wouldn't work.

I also found the girls were more settled at groups that I felt more comfortable at. So it was a positive for them to.

I know how much this type of situation can suck.
