Meta tags are displayed incorrectly in google

The meta tags of Google are not adopted for my site that I have created.

I changed the meta tags about 3 months ago.

robert.txt has been added to the Google Search console. I also did a new crawling on Google.

How can it be that after 3 months a wrong meta description always appears.

Here pictures:


Here is the Link of the site: Baureinigung St.Gallen - Reinigungszentrum

I look forward to your answers

Google freely changes the content of both the title and the meta-description based on its algorithm and the searchers intent. It is really not under your control. If your site is being crawled and you have provided the base information that is usually the best you can do.

OK. Many thanks for the quick response.

Best regards
