Turns round a point in strong winds is actually part of the syllabus, usually coupled with low level navigation, so i wouldn't be too worried about that.
However, if you're doing that lesson before you've even been solo that is definitely cause for concern. I would say talking to the CFI at the school to ask why you haven't met solo standard yet and what you can work on would be a good idea.
Otherwise, ask to change instructor, or even change school. If they are consistently over charging, surely that's a legal matter for charging for a service which has not been provided. Definitely worth complaining about.
