Ask HN: How to Force Heroku / Salesforce to Comply with GDPR Request?

I have a suspended Heroku account which I couldn't log into. I plan to move to another platform.

I have reason to believe the account may contain personal data. The code itself is my client's property and trade secret (I run a consulting biz) which I wish to erase too. Emails sent to Heroku suspended account department / Salesforce privacy email address went unanswered. Their support hotline and chat bot redirected me to a help portal.

At this point it seems they don't honor their privacy policy at all, https://www.salesforce.com/company/privacy/ If anyone knows how best I should proceed, please enlighten me.

P/S no reason has been given as to why the account was suspended. I am only on free tier, so no unpaid bills. The code is hello-world-ish, unfinished with no external traffic, no heavy load. I suspect some kind of trigger-happy bots scanned the source code and auto-suspended the account without any review.
