Where to write about DoS if there is silence on abusive addresses?

Question

Burglary protection

For many months now, garbage has been pouring into my home server from the same addresses in the form of attempts to block the channel and zaddosit equipment. The attack now lasts for several minutes every few hours. Neither Rethem Hosting LLC [email protected] nor their backbone provider Server Central Network [email protected] respond to claims. The provider automatically creates issues in technical support, but people later close them. There is no response from the host at all. Therefore, the question is where else should I write?
An example of a piece of log from a home gateway, IP addresses are different on each visit, but all of them are from Rethem Hosting addresses:

Answer 1

how many gigabit traffic then?

Answer 2

taken from https://www.arin.net/abuse.html
Generally, the first step is to report fraudulent activity to the abuser's ISP, which will be listed as the organization that was delegated the IP address space. Most ISPs are responsive to concerns about hackers and spammers on their networks. If you are unsuccessful in resolving this situation with the ISP, you may wish to contact local law enforcement in your area.
