Did SBS identified her after she provided information to Trustpilot to verify her review? Did she ask Trustpilot to withhold identifying information (Not share with SBS)?
If this is what happened, I would contact TrustPilot (
[email protected] ) stating that by sharing her details (breaching GDPR), your friend is now being threatened for providing an honest and fair review. I would also contact the Danish Data Protection Agency (where EU Trustpilot is based)
[email protected]. When contacting Datatilsynet you need to mention both Trustpilot and SBS
