Don't hold your breath, you're not the only one. They claimed I clicked on my own ads which was never the case, of course there is no way to appeal. They stole my money because yes, they still owe me money, these punks sent me a 25€ voucher to buy ads, like it solves anything.... I will never ever trust them or rely on any of their services like the Google Cloud Platform.

Google settled a case like yours for $11m on the grounds that it would be too expensive, after four years of fighting, to prove they didn't steal your money lol.

My wife's paypal account has been suspended for 10 years now, for some utterly ridiculous reason I've long forgotten. After a year of trying to persuade them to un-suspend it, we gave up.
