You mean you kept paying them for blocked accounts? Can't you just block the payment directly?
Though you might be able to sue them. They took your money without providing the service you paid for. Though I must say it's a bizarre business practice to block paid accounts without even explaining why. It's another lesson not to rely on these large faceless corporations.
I had Google One and domain services on payment. Didn't want to risk disruption by cancelling credit card and didn't know if changing credit # card whether youtube would automatically use new payment method. Basically have too much of life tied up in the ecosystem to risk even more damage over ~20 dollars a month. Let alone potentially get on some litigation shit list if I took them to court.
Also can't remove credit card because you need some sort of valid default payment. Ended up setting up a gift card as backup payment for other services, then changed credit card number. Thankfully youtube didn't use other services backup payment method, and basically they cancelled account after no pay.
It's bizarre (infuriating) a paid account can't get in person service. It's bizarre paying for Google One for in person service doesn't extend to youtube. But yeah rough lesson to learn. Still stuck in Google ecosystem due to reasons, but have more frequent / redundant backups. Meanwhile, shameless use of adblock & sponsorblock for youtube.
