@variablepulserate now complain where it can maybe make a difference: complain to their data protection officer at [email protected] (found at https://www.ebayinc.com/company/privacy-center/privacy-notice/data-protection-officer-contacts/ ). if they don’t answer in a way you like, complain as advised at https://www.gov.uk/data-protection/make-a-complaint. they failed to obtain explicit consent [ico.org.uk] prior to collecting and storing your data. you can also request data deletion.
