In March this year I started the process to download my personal data on a website. I received a mail a month later informing me that my request will be delayed and can take up to 90 days to be processed. It has now been over 90 days since I received that delay notice and I still haven't gotten access to my data.
According to this question a company can inform me that my request will take longer if they are unable to comply with my request within 30 days. I am now wondering if there is an upper limit to how long a company has to process my request or if they can simply delay my request indefinitely?
