I had a similar experience but I wanted it that way. The listing for my residential society (comprising of 30+ buildings) was being hijacked by Real Estate brokers and internet service providers. I went on a discord server where Google employees were known to hang out and informally help people - they gave me ownership of the listing. This has allowed me to reject updates various businesses in the area try to push every few months.

Google maps hijacking has become a huge issue in my country where scammers update the contact details of local businesses without their knowledge and then scam unsuspecting people calling to place orders or book a stay. The vast majority of business owners don't even know they can / should take ownership of their maps listing.
