Hey,
I am very sorry to hear about your experience, and unfortunately, it is not going to be an easy task to get your listings up and running again. It sounds like you have gotten an account-level suspension. This happens when Google believes there was some type of spammy activity coming from a manager or user account that is associated with the listings, not the actual businesses themselves.
There is more information about this policy here:
Business Profile third-party policies - Google Business Profile Help
In order to fix this, you are going to have to determine which manager account is associated with the assumed spammy activity. Sometimes you can see who's account received the suspension by trying to login here with your Google account:
Local Guides Connect. If your account is the issue, you'll see a large banner saying you've been removed from the Local Guides program. You can also try this link
Account settings: Your browser is not supported. it will tell you if your account has restrictions on it
Next, you will have to disassociate that account from all of the listings and fill out a reinstatement request for each one. By following this guide that explains the process of reinstatement:

I hope this helps,
Andrea
