Sounds like a very standard Google experience. To anyone stuck in a similar hell in the future - once the company has demonstrated that they aren't willing to help, there is no point continuing down that road. Escalate it to your credit card provider (with documentation) and they will clear it up pretty quick.
They'll clear it up by banning your Google account and blacklisting you for all Google services. Just be prepared for that.
A credit card chargeback bans you from Google Pay/Wallet/Android Pay/Google merchant services/google shopping basket/gBilling/whatever it's called now and all services requiring payment. I think you can still use gmail/youtube/whatever.
