Hi Mert. I'm Greg, awarded MVP for eleven years, Volunteer Moderator, and Independent Advisor here to help you until this is resolved.
If you want to complain to Microsoft use the Feedback Hub app in Start Menu where developers are tasked to process consumer feedback. But Microsoft will not even see it here because this is a tech forums where we are mostly volunteers trying to help solve your problems.
Here are the present ways to control Updates:

If that is not enough then you can indeed stop Updates by setting a Metered Connection which has worked for every one of thousands I've suggested it to for five years: https://www.howtogeek.com/226722/how-when-and-w...
I would turn them back on periodically when you have the time, to make sure you have the latest security updates.
I hope this helps. Based on what you report back I can answer any questions and may have other steps to perform.
