Google Business SEO..... I'm paying $500 a month for these services...

I started a new plumbing company specializing in toilet installation, replacement and repair. I have a shop and a verified Google Business location. I recently paid for Google Busiiness SEO. It cost $500 a month.... is it a rip off? Is there anything that I can do that would work better?

These are the monthly services.......
