I am in Europe, so by law (GDPR) I have the right to make them delete all of this data.
How do I do so?
Also, I never consented to this being collected. How can their practice of collecting this type of data be GDPR compliant?

But I'd recommend going to the source: Read the privacy policy of each party delivering data and check if they mention it. I already sent a mail to the DPO of an app provider which shows up in this list and doesn't mentions Facebook in their privacy policy.
GDPR requires the users consent to do so. Having a statement in a privacy policy is imho not enough to qualify as consent.
