This is why I don't use Google services anymore, they've all but removed their customer support. You can't get them on the phone for anything. If your problem is that you're locked out of your paid YouTube prime account, their advice is to contact customer service by logging into your account (I can't, that's the problem). If you want to cancel the subscription, the best advice the internet has is to close your bank/credit card account. I've had a monthly YT premium charge that's been blocked for a year because I made the mistake of attaching it to my bank and can't log in to cancel it.

This is the level of service offered by one of the richest companies in the history of the world.
