Their reply to my request to delete my data:
Thank you for your email requesting your right to be forgotten.
In order for us to carry out this request, we require proof of ID to ensure we only action requests made by the genuine owner of this email account. Acceptable forms of identification are,
- Recent utility bill from the last 3 months (e.g. Gas, Electric)
- Valid drivers License
- TV License within the last 12 months
- Council Tax Letter within the last 12 months
- Title Deeds
one of your rights under gdpr is that you are entitled (free of charge) to a listing of all the data the other party has about you.
when you ask them about this listing this request itself becomes data the party has about you. it should therefore he included in the listing. (it is self referential, but that’s how it is).
if the information that you requested such a listing is missing from the data they provide in response to you request, they are in breach of gdpr rules. from them on you might want to file a complaint.
( I’ve no idea whether this would result in any meaningful compensation, if at all. but at least it should keep them busy.)
