Deleting a Telegram premium subscription to free it immediately for another account without waiting the subscription period to end

I have two Telegram accounts. One with my own name and one with nick. Last month I paid for Tg premium on the account with nick, because I had many large files sent to me via Tg, and I thought the basic account’s storage space might not be enough for me.

Now I actually would have much more need for the premium account on the Tg account with my own name, e.g. because of the better translation services.

Trying to  make this account premium, I get a message saying you can have only one premium account per one Apple id.

Cancelling the subscription of Telegram premium doesn’t help now, because the deal ends only after almost a year from now.

Does Apple have a way to completely delete this premium subscription (I don’t need a refund for my subscription fee) so that I could use the option for my other Telegram-account?
