CashApp did nothing wrong in the original story, you have a complaint against the seller, and the seller has a complaint against their agent, who failed to deliver correctly.
With a debit card, chargebacks are not a legal right, but often platforms will do them for you. Not sure exactly why CashApp weren't happy with you for asking, but maybe they felt like you hadn't tried hard enough with the seller, or that you were trying it on.
That said, my understanding from general opinions about CashApp is that them terminating your account is probably a net benefit for you in the long term, rather than something to rue.
