@homeopathical I’m sorry you feel that way but of course I respect your decision.
As I explained further up, we are a very small team here and making individual phone calls was never really possible for us. We did run a month long dashboard warning across accounts of all sizes (I see you acknowledged this on the 4th of November). We also used this forum and social media to provide as much advanced notice as we could.
You can download a full set of CSVs for your account by running a backup. These files are interchangeable so you should then be able to import them into another software application.
We are also flexible in providing a small extension should this be required.
