A lot of companies claim to be compliant with GDPR, but when requested for example an art. 15 request: “The data subject shall have the right to obtain from the controller confirmation as to whether or not personal data concerning him or her are being processed, and, where that is the case, access to the personal data and the following information”
There is not always a correct response. Then what can you do, ofcourse there always is the AP (authority personal data), but they are slow and not always interested in your problem.
You can also contact us, so we can correspond with the company that does not comply and get them to comply for you.
