Monopoly behavior is buying out competition forcefully and dominating a market with an unfair advantage ensuring they are the only ones in the market. I personally don't believe Google is a monopoly in the Search Engine market but that's only my opinion.
If you're signed up to Google One[0], you get proper (human) support. Luckily I never had to reach out.
For instance the couple vanguard/blackrock (= google + msft + apple + etc) has a monopoly on web engines (geeko and blink are financed by google and webkit by apple hence all are financed by the vanguard/blackrock galaxy).
