In U.K. you can open petitions to the parliament but unless some, quite huge, number of signatures gathered they may not look at it.
You could try to complain to some GDPR controlling body, again, in U.K. it might be ICO - Information Commissioner’s Office, but I would strongly recommend to check details on their website.
You should be able to use some web search engine, I suggest privacy friendly one, to check about petitions/privacy regulations interference in your location.
