I want to move my data to another service

The service had one month to act on your request (Art. 12(3)), and a refusal must state its reasons (Art. 12(4)). Two honest checks first: the right applies to data you provided and processed on the basis of consent or contract — and direct service-to-service transfer is only owed where technically feasible; a downloadable export always is.

If your request fits and they still refuse or stay silent, complain to your national Data Protection Authority (Art. 77) with a copy of your request.
