I activated YouTube premium on the wrong account, who/how can I change it?

As the post suggests. 

I signed up to Vodafone unlimited. Got the youtube premium but chose the wrong Google account. 

How can I change it please? I tried to cancel the subscription but it says my next billing date is in one year.
