I would like to share here that the author of this site made it very easy to call. If you read this and are in the EU, I urge you to try this.

Find a representative you think is at least somewhat likely to change their mind, and call their phone nr listed on the site. I tried one rep and couldn't get through, tried another (their Brussels phone) and I got someone on the line. The site helpfully suggests a call script, which you can take hints from.

I got a staffer on the line, who didn't want to share what my rep was planning to vote and generally wasn't very excited about calling with me, but I imagine that if lots of people call lots of these staffers, things actually do get through to these MEPs.

Please help.
